AI Technical Summary

Problems solved by technology

[0008] To sum up, there is currently no unified technical method to monitor slope surface and deep deformation, so the uniformity and comparability of the deformation test results are not strong. In addition, for equipment installation, test light, on-site visibility conditions and automatic acquisition equipment There are relatively special requirements for electricity consumption and other aspects

Abstract

The invention discloses a non-intervisibility high and steep side slope deformation monitoring method and a device thereof, and relates to a geotechnical engineering side slope deformation monitoring technology. The device of the invention comprises a target spot (1), a test connecting line (2), a test fixed base (3), a displacement sensor (4), a data acquisition recording system (5) and a PU computer (6), which are connected in sequence; the target spot (1) is a ground surface target spot or a deep layer target spot; the ground surface target spot is one or more than one; the deep layer target spot is one or more than one. The invention is not limited by intervisibility conditions of side slopes, and is not restricted by topographical conditions and light conditions; thus, the side slopedeformation can be monitored in real time at any time and in any climate; besides, the invention can be also applied to the geotechnical engineering deformation monitoring fields of foundation pit excavation and underground mine exploitation and the like.

Description

technical field [0001] The invention relates to a deformation monitoring technology of a geotechnical engineering slope, in particular to a method and a device for monitoring the deformation of a high and steep slope with poor visibility conditions and complex terrain. Specifically, it is mainly aimed at the real-time monitoring of the deformation of geotechnical engineering slopes under complex terrain conditions. , bridges, structural engineering, etc. surface and internal deformation monitoring field. Background technique [0002] Surface deformation monitoring is to monitor the absolute displacement and relative displacement of the landslide surface. Each monitoring method has its own advantages and disadvantages. According to the specific situation of the landslide, a monitoring method with appropriate accuracy and economical rationality should be selected. [0003] In the monitoring of the surface deformation of earth-rock dams, most of them continue to use the sight...
