Measurement on soil deformation and numerical simulation during tunneling process

摘要

During the tunnel construction, the soil loss and construction methods cause the soil deformation around the tunnel. The existed constructions and pipes are terribly affected by soil deformation. Hence, the significant studying on the soil displacement is implemented during tunneling construction. On the background of Hangzhou Metro Line1, the in-site monitoring is implemented to find the discipline of the soil deformation development. The numerical method is applied to simulate the tunneling process, and the results meet the discipline of monitoring data. The conclusions are consulted for soil deformation prediction during the tunnel construction.
