Abstract

The invention discloses a device and a method for monitoring the deformation degree of a cut slope. The device comprises a Beidou positioning module, a laser radar system, a guide rail system and an operation module. The Beidou positioning module is used for acquiring three-dimensional coordinate values of the two ends of the cut slope on the earth; the guide rail system deviates from the side edge of the constructed cut slope, and the laser radar system moves along the guide rail system and performs full-range scanning on the path along the cut slope; and the operation module is used for calculating topographic data of the cut slope according to the scanning data of the laser radar system and the positioning information of the Beidou positioning module. By fusing the guide rail type mobile laser radar and the Beidou positioning system, the deformation and displacement of the cut slope in construction can be obtained in real time under the condition of unmanned supervision, and timelydata support is provided for rapid early warning and engineering progress management.

Description

technical field [0001] The invention belongs to the field of deformation monitoring of cutting slopes, and in particular relates to a device and method for monitoring the deformation degree of cutting slopes. Background technique [0002] For cutting slopes, deformation and displacement monitoring is an important safety and quality management task. At present, the main methods of cutting slope monitoring include on-site inspection and instrument monitoring. The instrument monitoring technology can be divided into manual monitoring and automatic real-time monitoring. [0003] The monitoring methods in the prior art mainly include (1) manually carrying levels, total stations and other surveying and mapping instruments to regularly monitor the on-site marking points, (2) using GPS and other satellite positioning systems to monitor the marking points in real time, (3) InSAR Equal synthetic aperture radar scans the target slope regularly. It is impossible to monitor in real time...
