Technical field
The present invention relates to a kind of slope collapes prediction unit and method, especially a kind of device and monitoring method of utilizing geological radar monitoring deep, crack cranny development.
Background technology
The safety monitoring research of Dangerous Rock Body is of long duration, its monitoring method also has several different methods, traditional method adopts intuitively milscale observation, directly directly measure exactly the fracture width variation of Dangerous Rock Body with milscale, among measuring method intuitively simple, but have low precision and the problem such as can not record.Along with further developing of science and technology, GPS, INSAR three-dimensional laser scanner etc. also is introduced in the safety detection of Dangerous Rock Body, although data acquisition is convenient, but precision still can not fine satisfied monitoring requirement, and cost is expensive, in the engineering application of reality, still can not play the effectiveness of good monitoring and forecasting for the avalanche of Dangerous Rock Body.And said method all is to react Dangerous Rock Body avalanche trend by the change in displacement on fracture detection top etc., and the development condition to the crack, deep, crack of directly causing the Dangerous Rock Body avalanche does not propose the monitoring means on any scientific meaning.
Summary of the invention
The objective of the invention is for overcoming above-mentioned the deficiencies in the prior art, a kind of device and monitoring method of utilizing geological radar monitoring deep, crack cranny development is provided, it utilizes the characteristics of geological radar noncontact long-range detection, realize efficiently the monitoring to deep, Dangerous Rock Body crack cranny development, according to its development condition and Variation Features, in conjunction with the correlated judgment criterion, thereby successfully realize the avalanche of Dangerous Rock Body is predicted.Have simple to operately, data are easy to record, the advantages such as efficiently and accurately.
For achieving the above object, the present invention adopts following technical proposals:
A kind of device that utilizes the avalanche of geological radar monitoring deep, crack cranny development prediction Dangerous Rock Body, comprise the slide rail of installing along Dangerous Rock Body fracture width direction, slide rail is provided with can be along its horizontal link that moves, laterally be installed with geological radar on the link, the geological radar both sides are connected with rope, and geological radar links to each other with computing machine.
Adopt wired or wireless linking to each other between described geological radar and the computing machine.
A kind of monitoring method of utilizing geological radar monitoring deep, crack cranny development device, step is as follows:
1) near Dangerous Rock Body crack point, install slide rail along the fracture width direction, horizontal link and geological radar are set on the slide rail, and by geological radar controlled lower regular movement on guide rail, deep, the crack cranny development signal data of geological radar collection is transferred to computing machine;
2) utilize computing machine that the image data of multiple spot is carried out overall treatment and judgement, determine the development condition in crack, deep, Dangerous Rock Body crack, further according to existing correlated judgment criterion, computing machine is according to the developmental state in crack, deep, fixed crack, dope the trend of Dangerous Rock Body avalanche, send in case of necessity early warning.
Among the present invention, geological radar by slide rail, be can be regarded as one group of side line data acquisition fully, and namely to described computing machine transmission primaries data.On the side line, the measuring point of geological radar is evenly distributed on the described slide rail.The movement of geological radar on slide rail relies on left and right sides rope control.
The invention has the beneficial effects as follows, the present invention utilizes the characteristics of geological radar noncontact long-range detection, realize efficiently the monitoring to deep, Dangerous Rock Body crack cranny development, according to its development condition and Variation Features, in conjunction with the correlated judgment criterion, can make the crack situation in deep, Dangerous Rock Body crack and react accurately and make analysis, thereby effectively predict the avalanche of Dangerous Rock Body crack.The present invention has simple to operate, and data are easy to record, the advantages such as efficiently and accurately.
