In the invention, the side slope is generally referred to as a slope with a certain slope, which is formed on two sides of the roadbed to ensure the stability of the roadbed.
The gradable response slope monitoring method provided by the invention can comprise the following steps: and providing stability safety parameters, rainfall parameters and vector displacement increment parameters. The stability safety parameter, the rainfall parameter and the vector displacement increment parameter are provided and mainly used for determining the slope monitoring early warning level.
In the invention, the stability safety parameter generally refers to the ratio of the anti-slip force to the slip force along the supposed slip crack surface, the stability safety parameter is an important parameter of the slope stability, and the smaller the slope stability safety coefficient is, the worse the slope stability is. Suitable methods for providing stability safety parameters should be known to those skilled in the art. Stability safety parameters are typically calculated from the dimensions of the slope and the properties of the slope soil, the specific calculation methods of which should be known to those skilled in the art. For example, the stability safety parameters can be calculated according to chapter eight of the study of soil texture and soil mechanics (fifth edition, Qian Jian Zheng).
In the invention, the rainfall parameters usually reflect the rainfall information of the position of the slope, and the rainfall parameters can comprise daily rainfall, rainfall level and duration. The rainfall parameter is a basic parameter of a rainfall criterion, the rainfall criterion refers to sudden heavy rainfall or continuous heavy rainfall in a certain area, and the rainfall reaches a certain amount to cause instability and rapid sliding of the surrounding rock of the potentially dangerous side slope; the method belongs to externally applied critical inducing criteria, the difference of side slope structures and geological environment conditions in different areas is large, the critical rainfall amount for inducing landslide is large, and uniform general criteria are still difficult to form. However, the rainfall is easy to monitor, particularly easy to continuously monitor in real time and transmit data, and is a relatively successful landslide early warning criterion used at present. Suitable methods of providing rainfall parameters should be known to those skilled in the art. For example, a rainfall monitoring device for measuring rainfall parameters may employ a rain gauge or the like. For another example, a rain gauge may be installed on a 100 × 50m slope without specific geomorphic units, and the installation position may monitor the change of the rainfall on the slope and the surrounding within a distance of 25m from the monitored slope, so as to provide rainfall parameters. For the rainfall level, the determination method can refer to table 1 in "rainfall level (GB/T28592 and 2012)", and the duration is measured by day in the present application, and is measured by day in less than one day.
In the invention, the specific calculation method of the vector displacement increment parameter is usually to quadratic sum of squares of the horizontal displacement increment and the vertical displacement increment, and the specific numerical value of the horizontal displacement and the vertical displacement can be usually obtained by a field monitoring sensor. Suitable methods for providing the parameters used in the calculation of the vector displacement delta parameters will be known to those skilled in the art. For example, methods for monitoring surface displacements are generally based on GNSS surface displacement monitoring devices (GNSS monitoring systems), the required items of equipment including: the GNSS base station can determine and calculate the plane displacement increment and the vertical displacement increment of the GNSS base station in a certain time through a satellite positioning system, and the vector displacement increment can be obtained by squaring the square sum of the plane displacement increment and the vertical displacement increment. For another example, for the arrangement of equipment in a slope monitoring system, taking a 100 × 50m slope without a specific topographic unit as an example, 6 GNSS receivers, 1 GNSS reference station, 3 sliding inclinometers and a plurality of crack meters (at least 1 crack is arranged) can be arranged, wherein GNSS monitoring points are arranged on a main section perpendicular to the main sliding direction, at least 3 GPS monitoring points are arranged on each section, GPS surface displacement monitoring points are respectively arranged on a slope trailing edge subsidence zone, a slope platform and a slope uplift zone, point addition is appropriately performed according to the length of a longitudinal section of the slope, average arrangement is not required, but the specific topographic unit needs to be arranged, the deep rock displacement inclinometer and the GNSS monitoring points should be arranged in the same vertical direction, adjustment can be performed according to the field condition, and the horizontal distance should be kept within a range of 10 m.
The slope monitoring method with gradable response provided by the invention can also comprise the following steps: and determining the slope monitoring and early warning level according to the stability safety parameter, the rainfall parameter and the vector displacement increment parameter. Generally speaking, the higher the stability safety parameter is, the higher the slope monitoring and early warning level is, otherwise, the lower the stability safety parameter is, the lower the slope monitoring and early warning level is; the higher the rainfall parameter is, the higher the slope monitoring and early warning level is, otherwise, the lower the rainfall parameter is, the lower the slope monitoring and early warning level is; the higher the vector displacement increment parameter is, the higher the slope monitoring and early warning level is, otherwise, the lower the vector displacement increment parameter is, the lower the slope monitoring and early warning level is. For example, in slope monitoring, the stability safety parameter, the rainfall parameter, or the vector displacement increment parameter obtained by measurement may be compared with the calculated critical displacement threshold, and if the stability safety parameter, the rainfall parameter, or the vector displacement increment parameter is smaller than the critical displacement threshold, it indicates that the safety condition is relatively good; if the stability safety parameter, the rainfall parameter, or the vector displacement increment parameter is equal to the critical displacement threshold, indicating that the safety condition needs to be noticed; if the stability safety parameter, the rainfall parameter or the vector displacement increment parameter is larger than the critical displacement threshold value, the safety condition is poor, and important attention needs to be paid.
In a specific embodiment of the invention, the slope monitoring and early warning level can be determined according to the relationship in the table shown below, and the highest hazard degree item in the stability safety parameter, the rainfall parameter and the vector displacement increment parameter is used for determining the slope monitoring and early warning level.

For the vector displacement speed-increasing parameter, when the vector displacement speed-increasing parameter is less than 2mm/d, the corresponding hazard degree is 1 grade; when the vector displacement acceleration parameter is not more than 2 and less than 3mm/d, the corresponding hazard degree is grade 2; when the vector displacement acceleration parameter is more than or equal to 3mm/d, the corresponding hazard degree is 3 grade.
The slope monitoring method with gradable response provided by the invention can also comprise the following steps: providing a potential economic loss parameter, a threat object parameter, a slope location parameter and a destabilization hazard parameter. And providing potential economic loss parameters, threat object parameters, side slope position parameters and instability hazard parameters, and mainly determining the design grade of the side slope monitoring system.

The slope monitoring method with gradable response provided by the invention can also comprise the following steps: and determining the design grade of the side slope monitoring system according to the potential economic loss parameter, the threat object parameter, the side slope position parameter and the instability hazard parameter. Generally speaking, the higher the potential economic loss parameter is, the higher the design level of the slope monitoring system is, and conversely, the lower the potential economic loss parameter is, the lower the design level of the slope monitoring system is; the higher the threat object parameter is, the higher the design grade of the slope monitoring system is, otherwise, the lower the threat object parameter is, the lower the design grade of the slope monitoring system is; the higher the slope position parameter is, the higher the design grade of the slope monitoring system is, otherwise, the lower the slope position parameter is, the lower the design grade of the slope monitoring system is; the higher the instability hazard parameter is, the higher the design grade of the slope monitoring system is, and conversely, the lower the instability hazard parameter is, the lower the design grade of the slope monitoring system is. For example, in slope monitoring, the calculated potential economic loss parameter or threat object parameter may be compared with the calculated critical displacement threshold, and if the potential economic loss parameter or threat object parameter is smaller than the critical displacement threshold, the safety condition is relatively good; if the potential economic loss parameter, or the threat object parameter, is equal to the critical displacement threshold, indicating that the security condition needs attention; if the potential economic loss parameter or the threat object parameter is greater than the critical displacement threshold, the safety condition is poor, and important attention needs to be paid. For another example, in slope monitoring, the slope location parameter may be compared to a preset value to determine whether the safety condition is relatively good, needs attention, or is poor. For another example, in slope monitoring, the instability hazard parameter may be compared to a preset value to determine whether the safety condition is relatively good, needs attention, or is poor.
In an embodiment of the present invention, the design level of the slope monitoring system may be determined according to a relationship in a table as shown below, and the highest hazard level of the potential economic loss parameter, the threat object parameter, the slope position parameter, and the instability hazard parameter is determined. In the table shown below, the design grades of the slope monitoring system are divided into 1 grade, 2 grade and 3 grade according to the hazard degree from high to low, and respectively correspond to three conditions of poor safety condition, need to be noticed in the safety condition and good safety condition. For the potential economic loss parameter, when the potential economic loss parameter is more than or equal to 5000 ten thousand yuan, the corresponding hazard degree is grade 1; when the potential economic loss parameter is less than 5000 and more than or equal to 500 ten thousand yuan, the corresponding hazard degree is grade 2; when the potential economic loss parameter is less than 500 ten thousand yuan, the corresponding hazard degree is grade 3.

For the side slope position parameters, when the side slope position is located in the urban and rural planning area, radioactive facility, military facility, nuclear power, highway above the second level (including), railway, airport, large-scale hydraulic engineering, electric power engineering, port and pier, mine, centralized water supply source area, industrial building, civil building, garbage disposal site, water treatment plant, oil pipeline, oil storage warehouse and other positions, the corresponding hazard degree is 1 level; when the position of the side slope is positioned at the positions of newly-built villages and towns, roads below the second level, medium-sized hydraulic engineering, electric power engineering, ports and docks, mines, centralized water supply source places, industrial buildings, civil buildings, garbage disposal plants, water treatment plants and the like, the corresponding hazard degree is 2 level; when the position of the side slope is positioned at the positions of small-sized hydraulic engineering, electric power engineering, ports and docks, mines, centralized water supply water source places, industrial buildings, civil buildings, garbage disposal plants, water treatment plants and the like, the corresponding hazard degree is 3 grade. For the instability hazard parameter, when the instability hazard parameter is particularly large, the corresponding hazard degree is grade 1; when the instability harmfulness parameter is large, the corresponding harmfulness degree is grade 2; when the destabilization hazard parameter is large, the corresponding hazard level is grade 3.

Generally speaking, under the condition that the design grades of the slope monitoring systems are the same, the higher the slope monitoring early warning grade is, the higher the response grade of the slope monitoring system is; under the condition that the slope monitoring early warning grade is the same, the lower the design grade of the slope monitoring system is, the higher the response grade of the slope monitoring system is.
In a specific embodiment of the present invention, the graded response level of the slope monitoring system may be classified into a level I, a level II, and a level III according to the monitoring intensity, and the graded response level of the slope monitoring system is determined according to a relationship in a table as shown below.
When the parameters corresponding to the slope monitoring early warning grade and the slope monitoring system design grade are less than or equal to 1, namely when the slope monitoring system design grade is grade 3 and the slope monitoring early warning grade is grade 1, the slope monitoring system response grade is grade I;
when the parameters corresponding to the slope monitoring early warning grade and the slope monitoring system design grade are 2, namely when the slope monitoring system design grade is 2 grade and the slope monitoring early warning grade is 1 grade, or when the slope monitoring system design grade is 3 grade and the slope monitoring early warning grade is 2 grade, the slope monitoring system response grade is II grade;
when the parameters corresponding to the slope monitoring early warning level and the slope monitoring system design level are more than or equal to 3, namely except the three cases, the slope monitoring system response level is level III.
In the present invention, the method may further include: determining and/or adjusting an operation strategy of slope monitoring. For example, when the response level of the slope monitoring system is level I and the response level of the slope monitoring system is low-intensity, a low-intensity slope monitoring operation strategy is adopted; when the response level of the slope monitoring system is level II and the response level of the slope monitoring system is medium intensity, adopting a medium intensity slope monitoring operation strategy; and when the response level of the slope monitoring system is level III and the response level of the slope monitoring system is high strength, adopting a high-strength slope monitoring operation strategy. Means of determining and/or adjusting operational policies include adjusting the response (on or off) of data collection operations of various measurement facilities (e.g., rainfall monitoring devices, crack monitoring devices, surface displacement monitoring devices (e.g., GNSS-based surface displacement monitoring devices, distributed optical fiber-based surface displacement monitoring devices), deep displacement monitoring devices, etc.), the frequency of data collection operations, and the like.
In a specific embodiment of the present invention, when the response level of the slope monitoring system is in a low-strength, medium-strength, and high-strength state, the relationship between the response strategy, the data acquisition frequency, and the duration of the slope monitoring system may specifically refer to the relationship in the following table, and when the response level of the slope monitoring system is high-strength, manual site survey and further expert evaluation may be supplemented as necessary:
the operation strategy of slope monitoring generally needs to consider the economy of slope monitoring, and the operation strategies of a slope monitoring system under low-strength, medium-strength and high-strength working grades are stipulated. When the whole side slope is in a stable stage or a relatively stable stage, the deformation of the side slope is slow, the data change in unit time is small, the significance of the obtained high-frequency data on the analysis of the deformation of the side slope is small, at the moment, a low-intensity operation strategy can be adopted, namely, the GNSS-based surface displacement monitoring equipment, rainfall monitoring equipment, crack monitoring equipment and deep displacement monitoring equipment are utilized, the low data acquisition frequency and the low data coverage rate are adopted (for example, data are obtained every 11-13 hours, the low-intensity work of the side slope monitoring system lasts for more than 24 hours), and the displacement monitoring is carried out on key measuring points on the surface so as to reduce the monitoring cost. When the state of the side slope changes to a certain extent, but the influence of the changes on the stability of the side slope is not clear, the working strength of the side slope monitoring needs to be improved, a medium-strength operation strategy needs to be adopted, displacement data of surface and deep measuring points with low coverage rate are collected by utilizing surface displacement monitoring equipment based on GNSS, surface displacement monitoring equipment based on distributed optical fibers, deep displacement monitoring equipment, rainfall monitoring equipment and crack monitoring equipment, data are acquired every 5-7 hours, and medium-strength work of a side slope monitoring system lasts for more than 48 hours, so that the monitoring and the grasping of the whole state of the side slope are completed. When the slope stability state or the slope stability influence factors change rapidly, the slope deformation development is fast, or the probability of the occurrence of the slope displacement curve change is increased rapidly, a high-intensity operation strategy needs to be adopted for a slope monitoring system, at the moment, a rainfall monitoring device, a crack monitoring device, a deep displacement monitoring device, a GNSS-based surface displacement monitoring device and a distributed optical fiber-based surface displacement monitoring device are adopted to monitor the distributed vertical displacement high coverage rate of the slope in real time, the high-intensity work of the slope monitoring system lasts for more than 72 hours, and manual field survey and expert evaluation can be assisted to realize the accurate analysis of the slope stability development trend. At this moment, the operation cost of the slope monitoring system is highest.
A second aspect of the invention provides a computer readable storage medium having stored thereon a computer program which, when executed by a processor, implements the scalable responsive slope monitoring method as provided in the first aspect of the invention.
A third aspect of the invention provides an apparatus comprising: a processor and a memory, the memory being configured to store a computer program, and the processor being configured to execute the computer program stored by the memory to cause the apparatus to perform the scalable response slope monitoring method provided by the first aspect of the invention.

In the present invention, the operation principle of each module in the above apparatus may refer to the slope monitoring method with gradable response provided by the first aspect of the present invention, which is not described herein again.
The slope monitoring method with gradable response provided by the invention is a slope monitoring method which is based on various monitoring devices and can be operated gradably, the slope monitoring method can adjust the slope monitoring system and the operation strategy thereof according to the actual monitoring result, can reduce the maintenance cost of the system, can properly prolong the whole service life of the slope monitoring system, and has good industrialization prospect.
The invention of the present application is further illustrated by the following examples, which are not intended to limit the scope of the present application.
Example 1
Beside a certain three-level road in Gansu, a soil slope with the scale of about 50 multiplied by 1000m exists, the slope foot adopts structures such as a retaining wall and the like to support and protect, and the slope has the risk of instability and damage according to field reconnaissance. In order to better monitor the deformation development of the side slope, reduce the harm caused by the instability of the side slope, plan the development of the side slope monitoring work, consider the economy of the side slope monitoring and correspondingly design a side slope monitoring system according to the characteristics of the side slope. The system comprises: (1) monitoring rainfall by adopting a rain gauge to monitor the slope and the surrounding rainfall (refer to the design of a weighing optical rain gauge, a radiant, etc.); (2) monitoring surface displacement, namely selecting a representative point, and monitoring the surface displacement of the slope by adopting a GNSS (in the concrete method, according to the application of a GNSS real-time deformation monitoring system in a rock high slope, Zhang Dehui and Ludahui); monitoring the surface displacement of the slope by adopting a distributed optical fiber (the concrete method refers to research on distributed optical fiber monitoring technology of slope engineering, inert sea waves and the like); (3) deep displacement monitoring, namely monitoring the deep displacement of the side slope by adopting a sliding inclinometer (the concrete method refers to research on a burying method of a slope measuring device of a side slope deep displacement monitoring hole, leaf salt); (4) and (3) monitoring the surface cracks, and monitoring the width change of the cracks by using a crack meter (the specific method refers to an automatic monitoring system for the displacement of the cracks of the side slope of the Baolih Hisher strip mine, Shinibo, Zhangfeng and Shinigh).
Experience of peripheral slope engineering shows that the slope is easy to have deeper landslide disasters, a plurality of sliding surfaces possibly exist, and the early development rate of slope instability is relatively slow. Monitoring of side slope surface cracks and the like can also provide reference for side slope stability analysis, local rainfall is less, but rainfall has a large influence on the properties of side slope soil bodies, and rainfall has a certain influence on the side slope stability. In addition, deformation of the side slope bottom retaining structure can also provide early warning for overall deformation and stability change of the side slope. In conclusion, the determination of rainfall condition, crack change, surface displacement and deep displacement is the most important, and the slope monitoring and early warning grade parameters can be determined according to the determination.
Because the side slope is positioned beside the three-level highway, the design grade of the side slope monitoring system of the side slope is determined to be level 2 according to the design grade parameter determination method of the side slope monitoring system.
After the slope monitoring system is built, the operation conditions from 1/5/2020 to 31/5/2020 are shown in the following table:
according to the slope monitoring and early warning level determination method and the slope monitoring system response level determination method, the slope monitoring and early warning level is 2 at 22 days 5 and 22 months 2020, so that the slope monitoring system has a response level of 3 at 22 days 5 and 22 months 2020 to 24 days 5 and 24 months 2020, and the slope monitoring system is required to monitor a slope in real time by adopting a high-intensity operation strategy. In the rest time of 5 months in 2020, the slope monitoring system adopts a medium-intensity operation strategy. Compared with the whole slope real-time monitoring of a high-strength operation strategy, the medium-strength operation strategy adopts a low coverage rate to monitor the sampling frequency of 5-7 hours/time, the number of monitoring devices operating under the medium-strength operation strategy is only half of that of the high-strength operation strategy, the data volume of monitoring and acquisition is greatly reduced, and the equipment operation cost and the data analysis cost are greatly saved.
After the slope monitoring system is built, reasonable and accurate monitoring of the state of the slope is achieved, and the monitoring result shows that the state of the slope is stable. The monitoring system effectively guarantees safe operation of the three-level road.
Example 2
A soil slope with the scale of about 400 multiplied by 100m exists beside a certain small industrial building in Guangxi, and the slope has the risk of instability and damage due to more local rainfall and industrial production and construction in the adjacent area. In order to better monitor the deformation development of the side slope, reduce the harm caused by the instability of the side slope, plan the development of the side slope monitoring work, consider the economy of the side slope monitoring and correspondingly design a side slope monitoring system according to the characteristics of the side slope. The system comprises: (1) monitoring rainfall by adopting a rain gauge to monitor the slope and the surrounding rainfall (refer to the design of a weighing optical rain gauge, a radiant, etc.); (2) surface displacement monitoring, namely selecting a representative point, monitoring the surface displacement of the slope by adopting a GNSS (according to the application of a GNSS real-time deformation monitoring system in a rock high slope, Zhang De Hui, Luxiahui in the concrete method), and monitoring the surface displacement of the slope by adopting a distributed optical fiber (according to the research on distributed optical fiber monitoring technology of slope engineering, Suihai waves and the like in the concrete method); (3) deep displacement monitoring, namely monitoring the deep displacement of the side slope by adopting a sliding inclinometer (the concrete method refers to research on a burying method of a slope measuring device of a side slope deep displacement monitoring hole, leaf salt); (4) and (3) monitoring the surface cracks, and monitoring the width change of the cracks by using a crack meter (the specific method refers to an automatic monitoring system for the displacement of the cracks of the side slope of the Baolih Hisher strip mine, Shinibo, Zhangfeng and Shinigh).
According to the scale of the slope, 48 GNSS receivers, 1 GNSS reference station and 24 inclination measuring holes are arranged, 3 crack meters are arranged in each crack for the existing cracks, and in addition, distributed optical fibers and other required accessory facilities are arranged in the range of the slope.
The stability safety coefficient of the side slope is 1.24 through calculation, the potential economic loss caused by the instability damage of the side slope is about 450 ten thousand yuan, 18 persons threaten the instability of the side slope have high harmfulness, and the design grade of the side slope monitoring system of the side slope is determined to be 3 grade according to a side slope monitoring system design grade determination method.
According to local meteorological data, the local rainfall is large, and heavy rainstorm weather occurs, according to a method for determining the slope monitoring and early warning grade, the slope monitoring and early warning grade of the slope can change from 1 to 3, so that the response grade of a slope monitoring system can change from 1 to 3, and the monitoring of the slope needs to consider operation strategies of low, medium and high intensity grades.
After the slope monitoring system is built, the operation conditions from 1 month 4 in 2019 to 30 months 6 in 2019 are shown in the following table:
after the monitoring system is built, the monitoring system can effectively monitor the slope body displacement development condition of the side slope and the rainfall condition in a certain area around the side slope, and then a side slope monitoring system operation strategy of a proper grade is selected for monitoring. In general, the slope monitoring system can work effectively, and saves resources and cost required by daily monitoring.
