The method comprises a monitoring module (100) arranged on a landslide (4), wherein the monitoring module (100) comprises a fixed inclinometer (7) arranged in the landslide (4), a round prism (12) arranged at the top of the fixed inclinometer (7), and first monitoring terminal equipment (13) arranged at one side of the round prism (12); and an observation module (200) arranged to be opposite to the monitoring module (100) and used for observing the monitoring module (100) in real time, wherein theobservation module (200) comprises a measurement robot (16) and second monitoring terminal equipment (17). The invention further discloses a landslide earth surface and deep displacement joint monitoring method. The monitoring system disclosed by the invention can precisely measure a sliding direction, the surface deformation and the deep displacement of the landslide as the evidence for the calculation, analysis and safe evaluation of the landslide, and the system is stable and reliable, hard to be influenced by the special weathers and the forest vegetation, and high in monitoring precision.

Description

technical field [0001] The invention belongs to the technical field of geological disaster monitoring and prevention and control, and more specifically relates to a combined monitoring system and method for landslide surface and deep displacement. Background technique [0002] Landslide refers to the phenomenon that the rock and soil mass on the slope slides down the slope in whole or in part along a certain weak surface or weak zone under the action of gravity due to the influence of various factors. A landslide disaster will cause great harm. Therefore, it is of great significance to establish a reasonable landslide monitoring system to understand the deformation characteristics and controlled factors of landslides in different development stages. [0003] Deep displacement monitoring has always been the basis and basis for landslide prevention and control. It can not only provide accurate and reliable slip displacement, sliding surface and sliding bed position and other ...

AI Technical Summary

Problems solved by technology

For actual landslide engineering, deep displacement monitoring generally drills holes on the landslide to the bedrock layer or stable soil layer, arranges the inclinometer pipe in the borehole, and then uses the pulley probe of the inclinometer to measure, so it can only measure landslides The relative horizontal displacement in the body, but it is difficult to determine the actual displacement of the landslide mass

[0004] Although the absolute deformation of the landslide surface can be measured by using total stations, GPS positioning and other methods, these monitoring methods either require manual monitoring, which is not conducive to the long-term monitoring of landslides, and is even more inapplicable for some landslides with safety risks; Insufficient accuracy, greatly affected by special climate and forest vegetation

In addition, the direction of landslides is also an important feature of landslide disasters. Its effective, correct and rapid determination is of great significance to the implementation of construction and later reinforcement strategies. However, the current monitoring methods rarely involve the determination of the direction of landslide deformation.
