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 slope deformation 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 geotechnical engineering slope deformation monitoring technology, in particular to a method and a device for monitoring deformation of a high and steep slope with no visibility and complex terrain. Specifically, it is mainly aimed at the real-time monitoring of geotechnical engineering slope deformation under complex terrain conditions. It not only has significant advantages in the deformation monitoring of slopes and auxiliary structures during construction and operation under complex terrain conditions, but also can be applied to roads. Surface and internal deformation monitoring of bridges, structural engineering, etc. 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...
