technical field

The invention relates to a method and device for measuring displacement, in particular to a method and device for measuring deep displacement of geological bodies such as landslides and high slopes. the

Background technique

Deep displacement monitoring technology is a branch of slope monitoring that has emerged in recent years. Compared with traditional monitoring methods, it has the characteristics of going deep into the slope, detecting slope changes in advance, timely data collection, direct information capture and high measurement accuracy. , in the study of slope deformation, the deep displacement monitoring technology mainly adopts borehole inclinometer and multi-point displacement meter. The working principle of the borehole inclinometer is to measure the angle change between the axis of the instrument and the plumb line, and then calculate the horizontal displacement at different elevations of the rock and soil mass. This method needs to bury a vertical inclinometer pipe with four guide grooves in the rock and soil body. For high slopes, the measurement density of four points is low, the accuracy is lacking, the instrument cannot be recycled, and the cost of adding measuring points is high. The multi-point displacement meter is used to bury and fix the anchor head at different depths in the hole after drilling the hole in the rock and soil, and install the displacement reading device on the measuring rod connected to the anchor head (the outer protective tube of the measuring rod is separated from the grouting cement mortar). The two methods are often ineffective for detecting large horizontal displacements of high slopes due to the crushing of the inclinometer pipe and the protective pipe, and because grouting is required in the borehole, the installation is time-consuming, laborious, and costly. the
