地铁隧道暗挖施工地表沉降模拟分析
Ground settlement caused by the excavation of mined subway tunnel
摘要
Abstract
Tunnel constructed by shallow tunneling method would cause settlement more or less,so how to predict the amount of settlement means a lot to the construction.Based on the situ measurement and numerical simulation via FLAC3D,this article takes 6th line of Beijing subway for example,using FLAC3D to calculate the ground settlement caused by the shallow tunneling method.The result shows that the simulation is similar to the value we measured,and the settlement can be divided into three stages,while most settlement occurs when the excavation face overpasses.Reasonable simulation can approximately predict the settlement and provide advice for similar excavation.关键词
