Comprehensive monitoring system for side slope and landslip

Abstract

A comprehensive monitoring system for a side slope and a landslip is capable of comprehensively monitoring surface displacement and depth displacement of a slope body, soil pressure of a retaining structure, and internal force of an anchoring structure, and realizing high-efficient acquisition and automation treatment of data. The comprehensive monitoring system for the side slope and the landslip comprises a side slope surface displacement monitoring unit, a side slope supporting structure stress monitoring unit, a side slope interior deformation monitoring unit and a data acquisition and transmission device, wherein the side slope surface displacement monitoring unit is arranged on a side slope surface and adopts a stay cord type fiber bragg grating displacement sensor; and two ends of the side slope surface displacement monitoring unit are respectively fixed on the side slope surface and the top of a slope body retaining structure; the side slope supporting structure stress monitoring unit consists of fiber bragg grating pressure boxes vertically embedded on the back of the slope body retaining structure at intervals, and a fiber bragg grating force gauge arranged on a slope body anchoring component; the side slope interior deformation monitoring unit is a fiber bragg grating intelligent anchoring rod embedded in the slope body by drilling a hole; and the data acquisition and transmission device consists of a multi-channel wavelength demodulator and a monitoring computer.

Description

technical field [0001] The invention relates to a side slope and landslide comprehensive monitoring system for comprehensive monitoring of surface displacement, deep displacement, retaining structure earth pressure and anchoring structure internal force of the slope body. Background technique [0002] Traditional side (landslide) slope monitoring methods can be roughly divided into the following three categories: patrol observation method, external observation method and internal observation method. [0003] Patrol and observation method, regularly arrange geological personnel to patrol and observe the slope and the range of possible influence along a certain route, observe whether there are cracks on the slope surface, buildings and structures near the surface, whether there is ground swelling, local collapse, and carefully search for other Deformation signs and the development and changes of ground fissures appear, and at the same time observe the groundwater exposure and ...
