Abstract

The invention provides a method and a system for remote intelligent monitoring and three-dimensional digital comprehensive warning of deep foundation pit stability. The method includes: establishing a construction area deep foundation pit excavation stability three-dimensional comprehensive numerical model on the basis of deep foundation pit rock and earth mass physical mechanics parameters, deep foundation pit area hydro-geological and engineering geological conditions and the FLAC3D (fast lagrangian analysis of continua in three dimensions) technology, and building a deep foundation pit three-dimensional visual safety warning platform based on VTK (visualization toolkit) business software; acquiring data of horizontal displacement and sedimentation of a deep foundation pit slope crest and a guard post, peripheral soil pressure of the guard post, joist steel axial force and peripheral soil pore water pressure of the deep foundation pit slope crest and the guard post, and transmitting the data to a remote user computer; and enabling the deep foundation pit excavation stability three-dimensional comprehensive numerical model to use initial data to complete model parameter modification and compare subsequent real-time data with model parameter threshold values, displaying by the aid of the deep foundation pit three-dimensional visual safety warning platform, and performing text message grading warning and onsite sound and light grading warning for super-warning parameters simultaneously.

Description

technical field [0001] The invention belongs to the technical field of deep foundation pit construction engineering related to urban subway stations, high-rise building foundation excavation, etc., and is used for deep foundation pit stability intelligent monitoring and safety early warning; The method of monitoring three-dimensional digital comprehensive early warning also involves remote intelligent monitoring of deep foundation pit force, deformation and mechanical stability three-dimensional digital comprehensive early warning system. Background technique [0002] With the expansion of the construction scale of urban subways and super high-rise buildings, along with more and more construction items of deep foundation pits, the instability of deep foundation pits, frequent occurrence of water and mud inrush accidents, and the stability of deep foundation pits have caused more and more problems. People are concerned that the technical regulations for foundation pit suppor...
