| Abstract: | In this paper,using finite element software,the tunnel elastoplastic numerical model was set up for sand geology tunnel of a urban metro,and studied the development rules of the ground surface settlement,vault settlement and horizontal convergence in the process of construction of short steps method.Construction measures and methods were adjusted through contrasted construction experimental data,which in order to ensure construction safety and provide a reference for similar projects. |
