Problems solved by technology

[0004] It can be seen from the above methods that the current research on slope stability monitoring is only from the surface of the rock mass or from the depth of the rock mass, and has never combined the two to judge the stability of the slope.
Therefore, it is impossible to fully detect the stability of the slope rock mass

Embodiment 1

[0036] Such as figure 1 As shown, the slope rock mass monitoring system provided by this embodiment includes a microseismic monitoring unit, a radar monitoring unit, and a processing unit 3. The microseismic monitoring unit and the radar monitoring unit are respectively connected to the processing unit 3 in communication, the microseismic monitoring unit and the radar The monitoring units are respectively set corresponding to the slope rock mass 7 to be tested. The processing unit 3 controls the microseismic monitoring unit and the radar monitoring unit to monitor. The microseismic monitoring unit detects the microseismic wave information inside the slope rock mass 7 to be tested and feeds it back to the processing unit 3. The radar monitoring unit scans the radar signal reflected on the surface of the rock mass 7 to be measured and feeds it back to the processing unit 3, which processes and analyzes the microseismic wave information and the radar signal.

Embodiment 2

[0051] The slope rock mass monitoring method provided in this embodiment applies the slope rock mass monitoring system provided in the first embodiment and includes the following steps:

[0052] S1. Punch holes on the slope rock mass 7 to be tested as measuring points, such as figure 2 As shown, the three-dimensional coordinates, azimuth angle, inclination angle and hole depth of each measuring point are measured at fixed points using the Southern CASS GPS software; among them, the hole diameter is 90mm, and the hole depth ranges from 6-9m.

[0053] S2. The microseismic sensors 1 are respectively arranged in corresponding holes;

[0054] S3. Perform daily blasting operations on the blasting area 6 of the road surface 8 in the area of ​​the slope rock mass 7 to be measured, and control the microseismic sensor 1 through the processing unit 3 to perform real-time monitoring and feedback the monitored microseismic wave information to the processing unit 3;

[0055] S4. The processing unit...

Abstract

The invention relates to the technical field of rock mass stability monitoring, in particular to a slope rock mass monitoring system and monitoring method, wherein the microseismic monitoring unit can quickly identify the vibration signal of the blasting area, and collect the centralized distribution of the slope rock mass microseismic events In the area, the radar monitoring unit can collect the external deformation and displacement data of the rock mass in all aspects of the slope by emitting electromagnetic waves. The slope rock mass monitoring system and monitoring method provided by the present invention combine monitoring through microseismic monitoring and radar monitoring, so that the monitoring area can be more refined, so as to achieve centralized monitoring, focus on monitoring potential displacement landslides, and make more convenient and effective judgments The location of the landslide, comprehensively monitor the internal and surface stability of the slope rock mass, and improve the accuracy of the monitoring results.

Description

Technical field [0001] The invention relates to the technical field of rock mass stability monitoring, in particular to a slope rock mass monitoring system and a monitoring method, and more specifically to a slope rock mass monitoring system and a monitoring method combining microseismic monitoring and radar monitoring. Background technique [0002] Slope is a relatively common structure in the field of geotechnical engineering, and it is widely used in the construction of water conservancy engineering, civil engineering, traffic engineering, and mining engineering. Because the surface of the slope is inclined at a certain angle, under the conditions of its own weight and other external inducing factors, the slope body has the geological phenomenon of sliding and destroying along the slope surface, which is called a landslide. Landslides will have a great impact on people’s production and life, and even endanger people’s lives. In order to effectively prevent landslides and other...
