Description

technical field [0001] The invention relates to the field of three-dimensional deformation monitoring of landslide drilling, and belongs to geotechnical engineering deep displacement monitoring equipment, in particular to a multi-node ultra-long deep displacement monitoring device and monitoring method based on an acceleration sensor array. Background technique [0002] In the monitoring of deep displacement of landslides, the traditional measurement method often uses a sliding inclinometer or a fixed inclinometer to monitor the deep deformation of the slope. The pull-sliding inclinometer measures the inclination displacement inside the borehole at fixed lengths and fixed points on the guide rail of the inclinometer pipe, so as to grasp the deformation inside the borehole. However, both the sliding inclinometer and the fixed inclinometer have their own defects: the fixed inclinometer has high precision and can carry out long-term monitoring along with the slope deformation, ...

AI Technical Summary

Problems solved by technology

However, both the sliding inclinometer and the fixed inclinometer have their own defects: the fixed inclinometer has high precision and can carry out long-term monitoring along with the slope deformation, but the fixed inclinometer can be installed in the same deep displacement drilling to measure The number of points is limited; the sliding inclinometer itself has high measurement accuracy, but with the continuous evolution and deformation of the landslide, the inclinometer pipe in the borehole is either broken or squeezed and deformed. At this time, the sliding inclinometer cannot sink into the borehole. measurement in the hole

However, the installation structure of foreign products is complex, requiring corresponding installation space, and the equipment cost and installation cost do not meet the national conditions of geological disaster monitoring in my country. Simple and cheap monitoring equipment is particularly important
