Problems solved by technology

[0003] At home and abroad, there is still little research on remote three-dimensional digital early warning of high slope stability. According to domestic literature, very few roads, mines, submarine tunnels, and railway projects in China have built databases, multi-information early warnings and safety management for tunnel construction, but not yet. See the literature report on the remote three-dimensional digital early warning of high slope stability based on the sliding surface method, which integrates the three-dimensional numerical model of high slope stability and the three-dimensional visual safety early warning platform

Abstract

The invention provides a slide-face type remote three-dimensional digital pre-warning method and a slide-face type remote three-dimensional digital pre-warning system for the stability of a high slope. The method comprises the following steps: establishing a stability three-dimensional numerical model of a high slope in a construction area according to the physical mechanics parameters of the rocks and soil in the high slope, hydrogeological and engineering geological features in the high slope area, meteorological data and FLAC3D (Fast Lagrangian Analysis Of Continua In 3 Dimensions) technology; establishing a three-dimensional visual safety pre-warning platform based on a VTK (Visualization Tool Kit) commercial software system; acquiring real-time offsetting slipping monitoring data of the slide face of the high slope and the ambient pore water pressure data of the slide face; transmitting the data to a remote computer, and loading to the stability three-dimensional numerical model of the high slope; analyzing the actually-measured data by the model, and comparing with the data of the model, so as to generate a sliding stability grading pre-warning parameter of the high slope; displaying and grading the safety pre-warning through the three-dimensional visual safety pre-warning platform; and transmitting the pre-warning information to cell phones of relative personnel in the form of short messages through a short message module which is linked with the remote computer, thus accomplishing the slide-face type stability remote three-dimensional digital pre-warning of the high slope.

Description

technical field [0001] The invention belongs to the field of high slope geological disaster engineering related to highways, railways, water conservancy and hydropower, etc., and is used for safety early warning of high slope stability; in particular, it relates to a remote three-dimensional digital early warning method for high slope stability by sliding surface method. It also involves a remote three-dimensional digital safety early warning system for high slope stability based on the sliding surface method. Background technique [0002] With the rapid development of my country's economic construction, high-grade highways, mountain railways, large and medium-sized hydropower stations and various side (bank) slope projects are also being rapidly constructed, but landslides and other geological disasters occur frequently, and the stability of high slopes is becoming more and more serious. Therefore, it is of great practical significance to carry out research on remote three-d...
