Description

Technical Field

[0001] The invention belongs to the technical field of slope protection, and in particular relates to a monitoring method for a high slope rock mass early warning system. Background Art

[0002] Since the slopes are prone to landslides, collapses, and falling debris, there are great safety hazards for roads, pedestrians, buildings, etc. at the bottom of the slopes. Therefore, the slopes around roads and buildings need to be protected to improve slope safety and reduce the possibility of safety accidents.

[0003] Compared with low slopes and gentle slopes, high slopes have the characteristics of greater landslide possibility and greater landslide impact. Before carrying out protective construction on high slopes, it is generally necessary to pre-explore the high slopes with special equipment and perform temporary support treatment on the landslide-prone positions to improve the safety during protective construction. However, this pre-detection method cannot continuously monitor dangerous points during the protective construction process. Some people also use vibration sensors, gap online detection instruments, etc. to perform real-time online monitoring of dangerous points. However, for high slopes with large areas and more dangerous points, more online detection instruments are required, the construction cost increases, and the installation of each detection instrument is also cumbersome, which increases the difficulty of construction and affects the construction progress.
