3D Numerical Simulation Analysis and Pre-Estimation New Technology of Ground Collapse Caused by Subway Shield Construction
The prediction of ground collapse caused by subway shield construction has been an important technical problem in urban subway shield construction, if the ground collapse could be pre-estimated, it could be able to take appropriate precautionary measures in advance to avoid the occurrence of ground surface settlement before the project construction, but it’s difficult to predict and calculate the settlement accurately. This paper analyzed main causes of ground collapse caused by shield construction, summarized the influence of several important parameters to surface settlement and then Midas GTS 3D numerical simulation software was used to simulate shield construction process and calculate ground surface settlement, to calculate stress, strain and displacement of overlying strata above the shield driving machine, obtained calculated values of surface settlement to predict ground collapse. Practice has proved that this pre-estimation new technology is in accordance with fact, it provides a useful reference for subway shield construction project.
