| Abstract: | The finite element numerical analysis method was adopted to simulate the actual problem on the conditions of different cases and various sites assumed at first aiming at the execution process based on Songhuajiang tunnel in Harbin planned to be constructed,the soil was assumed to be homogeneous,elastic, continuous,isotropy throughout.The varying law of surrounding soil displacement produced by shield tunneling was studied, and the main affecting factors were singled out. It provided the theory basis for determining the safety cover layer thickness of tunnel properly. |
| Keywords: | tunnel engineering shield tunneling finite element numerical analysis varying law of soil displacement tunnel |
