Description
Technical Field
The utility model belongs to the technical field of side slope landslide monitoring and early warning, especially, relate to a landslide monitoring and early warning system based on side slope internal stress strain control.
Background
In the technical field of slope monitoring in the prior art, slope protection technology is more and more emphasized, the development of the slope monitoring technology is more and more novel, and related engineering technology is more and more innovated. With the development of various capital construction projects in China, the infrastructure is subjected to many landslide deformations caused by geographical position factors. In the foundation construction of roads, hydropower, cities and towns and the like, a large number of slope projects are generated, and the projects are influenced by factors such as river scouring, underground water activity, rainwater soaking, earthquakes, artificial slope cutting and the like, and have the natural phenomenon that the whole or scattered land slides down along the slope. The slope stability on-line monitoring and early warning system establishes an intelligent slope safety monitoring system by using advanced technologies such as Internet of things, cloud computing and big data analysis, and provides scientific basis for daily maintenance, management and monitoring of the slope.
At present, the following methods are mainly used for the monitoring engineering technology of the slope body:
1. the GPS receiver is utilized to monitor the three-dimensional displacement of the earth surface of the slope body in different form stages, and the method has the advantages of high precision, quick report, easy operation and no influence by the terrain. All-weather monitoring can be achieved, but in extreme weather, GPS signals can be lost.
2. The strain measurement method uses a tubular strain gauge, a multipoint displacement meter, and a slide micrometer. The device is mainly suitable for measuring the displacement of different depths of the side slope and the position of a sliding surface (belt), has high precision, is easy to protect, is visual in measuring and reading data, and is convenient to use. But are costly and susceptible to ground moisture.
3. A rainfall meter and a rainfall alarm. The method is suitable for monitoring different types of slopes and different deformation stages thereof, and provides basic data for stability analysis of slope engineering. High precision, continuous observation, intuition and reliability. But only can be used for data analysis relatively close to the surface layer, and deeper analysis is difficult to achieve.
4. A sliding inclinometer features that an inclinometry tube is buried in a drilled hole and its internal guide slot is arranged, a movable probe with inclination sensor is passed through the inclinometry tube from bottom to top, the variation of inclination angle of drilled hole is recorded point by point, and the lateral displacement of each measuring point is calculated according to the inclination angle. The sliding inclinometer can accurately detect the inclination angle change of each measuring point along the line by the sliding of the probe in the inclinometer, but the automatic monitoring cannot be realized because the probe is required to move up and down along the inclinometer in each measuring process.
5. A fixed inclinometer features that an inclinometer tube is embedded in a drilled hole
The inclination angle sensors are buried at different positions, when the side slope is displaced laterally, the inclination angles among the sensors are changed, and the relative displacement among the measuring points is calculated according to the arrangement distance of the sensors. The sensors of the fixed inclinometer are relatively expensive, the fixed inclinometer needs a certain distance for installation, and the sensors with limited number can be installed in the drill holes only according to the requirement to measure the change of relative displacement among measurement points, so that the judgment of the position of the sliding surface can have deviation. When the deformation of the inclinometer pipe is large, the probe of the sliding inclinometer is clamped and cannot be scratched up and down, so that the measurement cannot be carried out; the fixed inclinometer has higher accuracy of an inclination angle sensor, and when the slope deformation exceeds the measuring range of the fixed inclinometer, the fixed inclinometer cannot continuously monitor.
