Influence of shield machine passing through the station on existing pile foundation
Based on the project of TBM passing through the station between Zhenfengshan and Daxiangshan Tunnel on Fuzhou Binhai Ex-press Line,this paper deeply analyzes the influence law of shield machine passing through the station on the stratum and the deformation and mechanical characteristics of the pile foundation of the existing bridge.A three-dimensional finite element model is established to simulate the actual shield machine passing through the station.By studying the deformation of foundation soil,the lateral displacement of pile foundation and the change of internal force of pile body,the influence area of shield machine on stratum and pile foundation is deter-mined.
