Abstract
The invention discloses a mountain landslide dense supervision method. The method is composed of supervision units which can be densely distributed (each unit is 50m*50m, or 100m*100m, etc.) and a plurality of temporary supervision centers. The supervision unit includes one or more polymer piezoelectric sensing units which are used to sense a relative displacement of the base slope rock layer to the loose soil-stone layer and the stress variation of a sliding layer, and a processing unit. The processing unit preprocesses the received perception signal or data from the sensing unit, and then sends the received perception signal or data to the supervision center. The supervision center is responsible for receiving the data sent by a plurality of supervision units in a larger area, and analyzing, processing the data. The data exchanges also exist among the supervision centers so as to acquire the relative displacement of the base slope rock layer to the loose soil-stone layer and the earth stress variation of a larger area, thus carrying out the mountain landslide analysis and prediction. The mountain landslide supervision method has the characteristics of low cost, easy installation, and flexible network construction, and can realize a real-time dense supervision of an arbitrary large area mountain landslide precursor.
Description
[technical field]
The present invention relates to landslide monitoring instrument instrument and sensor and circuit design field, be specifically related to a kind of low cost, can the dense layout monitoring point, thereby cover the landslide omen method of real-time of any large area region.
[background technology]
Landslide, avalanche are one of main disasteies in mountain area.They not only produce to industrial or agricultural and people's lives and properties bring about great losses, and are also causing very big harm aspect railway, highway, the Hydraulic and Hydro-Power Engineering.The generation on landslide and development both be subjected to formation condition, as controls such as topography and geomorphology, geologic lithology, tectonic structure, hydrogeological conditions, were subjected to risk factor again, as the influence of rainfall, mankind's activity.The a large amount of rainfalls of heavy rain, especially continuity are one of key factors that cause on the landslide.
On the good relatively hillside of vegetation, vegetation can water conservation, has offset the erosion damage of heavy rain to the hillside.When vegetation is destroyed, heavy rain just along veneer of soil stone to the infiltration of depths, hillside, reach tight and intact rock stratum until rainwater.At this moment rainwater and along the rock stratum, bosom to the mountain current downflow, in the course of time, tight rock stratum, bottom and top layer loose ground stone layer are separated by rainwater, veneer of soil stone layer be mingled with rainwater under the self gravitation effect to the hillside lower slider, form the rubble flow landslide.
Therefore, the key on monitoring rubble flow and landslide is relative slip and the terrane stress variation between intensive monitoring rock stratum.
[summary of the invention]
Fundamental purpose of the present invention is exactly the problem that solves the intensive construction of facing measuring point that is difficult to realize in the omen monitoring technology of existing landslide, a kind of landslide omen monitoring method is provided, have low cost, can the dense layout monitoring point, the abnormal conditions of the sloping bed rock layer in monitor large-area zone and rock stratum top loose ground stone layer relative displacement in real time and STRESS VARIATION, thus carry out landslide analysis and forecast.
For achieving the above object, the invention provides a kind of specific monitoring means structure, it is characterized in that: comprise at least one monitoring means and at least one monitoring center, described each monitoring means comprises at least one multipolymer piezoelectricity slope bed rock layer and rock stratum top loose ground stone layer relative displacement sensing unit and multipolymer piezoelectric stress and changes sensing unit, a processing unit, and connect with at least one monitoring center.Other monitoring technology that monitoring means is compared current use have extremely low cost, can be in less zones, and such as 50m * 50m, 100m * 100m, or the like, monitoring point of layout, thus make a monitoring center can cover a bigger zone.Described monitoring means comprises one or more multipolymer piezoelectricity slope bed rock layers and rock stratum top loose ground stone layer relative displacement sensing unit and multipolymer piezoelectric stress and changes sensing unit, a processing unit.Sensing unit can obtain the information of basal bed and sliding layer relative displacement generation, can obtain the variation of 0.01kPa to 1000kPa stress.Processing unit carries out the data of sensing unit sending to the monitoring means of monitoring center of monitoring center by big regional dense layout by wired or wireless mode after the pre-service, realizes the intensive monitoring in big zone, as the foundation of landslide analysis and forecast.The multipolymer piezoelectric sensor of described sensing unit, perception slope bed rock layer and rock stratum top loose ground stone layer relative displacement and STRESS VARIATION, the passive cable of perceptual signal process (such as, superpower toughness high density polyethylene, can be when direct-burried waterproof, low electric capacity 89pF/m, can reach 100m or longer) be transferred to ground, carry out sample quantization again after being connected to processing unit.The sloping bed rock layer of the reflection institute overlay area that provides by the large quantities of monitoring means that connect this monitoring center and rock stratum top loose ground stone layer relative displacement situation and STRESS VARIATION, analysis-by-synthesis is got rid of local interference, carries out the analysis and the forecast of landslide.The interconnection of a plurality of monitoring center can cover bigger zone.
The invention has the beneficial effects as follows:
The relative displacement and the STRESS VARIATION of low-cost monitoring basal bed, hillside in real time and ravelly ground can dense layout, and cover any large area region, thereby grasp the real-time change of rock stratum relative displacement of whole monitored area and stress.Solve not have the low cost that realizes for a long time, the problem of setting up of real-time monitoring point that highly dense intensity, large tracts of land cover, forecast for landslide omen analysis and landslide and to set up detailed, accurate, believable Monitoring Data basis.
