Model test device for cascade collapse of adjacent tunnels caused by continuous collapse of foundation pit
The invention discloses a model test device for cascade collapse of adjacent tunnels caused by continuous collapse of a foundation pit, and relates to the technical field of foundation pit supporting, the model test device comprises a test box body and sandy soil arranged in the test box body, a foundation pit continuous collapse simulation system, two tunnel collapse simulation systems and a data monitoring system are arranged in the test box body, according to the invention, by simulating the condition that two foundation pits exist on two sides of a tunnel in actual engineering in the test box body, the continuous collapse risk of a certain foundation pit caused by factors such as over-excavation and the influence of the foundation pit on deformation and internal force of an adjacent tunnel model can be studied; according to the device, the whole process of cascade collapse catastrophe evolution of the foundation pit and the tunnel system can be revealed, and effective test data are provided for research on disaster prevention and control and control methods of subsequent urban underground engineering aiming at the continuous collapse problem.
本发明公开了一种基坑连续垮塌引发邻近隧道级联垮塌的模型试验装置，涉及基坑支护技术领域，包括试验箱体和设置在试验箱体内的砂土，试验箱体内设置有基坑连续垮塌模拟系统、两个隧道垮塌模拟系统和一个数据监测系统，本发明通过在试验箱体中模拟实际工程中隧道两侧存在双基坑的情况，能够对某一基坑由于超挖等因素导致基坑存在的连续垮塌风险，以及其对邻近隧道模型的变形和内力影响进行研究，并对邻近隧道模型是否会发生级联垮塌进行评估，该装置能够揭示基坑与隧道系统级联垮塌灾变演化全过程，并为后续城市地下工程针对连续垮塌问题的灾害防控及控制方法研究提供有效试验数据。
