Test system for simulating karst covering soil collapse caused by subway vibration in karst area

Abstract

The invention belongs to the technical field of subway construction, and discloses a test system for simulating karst covering soil collapse caused by subway vibration in a karst area. The system comprises a geological detection module, a geological classification module, a karst sample acquisition module, a karst sample analysis module, a central control module, an information gathering module, a subway information acquisition module, a three-dimensional model construction module, a subway simulation operation module and a data recording and display module. According to the method, the geological classification of the karst area is achieved through geological detection, geological samples of different types are collected, the obtained karst samples are more representative, and the construction of the three-dimensional model of the karst area is more accurate; the subway vehicle information, the subway operation information and the subway tunnel information are integrated by obtaining the subway information, the simulation of subway vibration in the karst area is facilitated, the simulation effect is more real, the obtained karst covering soil collapse result is more accurate, and suggestions are provided for subway planning.

Description

Technical field [0001] The present invention belongs to the technical field of subway construction, and more particularly to a test system for simulating the collapse of rock sand-covered soil in simulated rocky region. Background technique [0002] At present: China has been built in shallow burythrocyte, but also the collapse factors that are collapsed by the rock-breasted collapse, not only the damage of the martyrhable collapse, is also extremely large. The subway line often constructs a bustling area in an intensive city, is an important part of urban construction. The vibration of subway vehicles may have a very serious impact on urban shallow burial solubility and directly affect the safety of rail transit. At present, research on the deformation of the subway vibration is mainly focused on non-rocker tunnels. The research work related to the mural simulation tunnel is mainly concentrated in the construction period, and whether the shallow buried rock sand will collapse du...
