| Abstract: |
During tunnel excavation and support the stability of front slope is a prerequisite for safety tunnel construction. This paper covers strength reduction method based numerical simulation and observation of displacement and plastic zones in front slope soil using ANSYS finite element software to determine the sliding surface and failure mode of front slope soil. Analyses of calculation results show the effect of excavation on the sliding surface of front slope and the effect of support structure on plastic zone of front slope. |
