| Abstract: | Based on the engineering geological conditions of the high slope of a tunnel on Hefei-Fuzhou high peed railway,slope stability is analyzed. According to the characteristics of the high slope of a tunnel,typical cross section is selected to establish an analysis model with limit equilibrium method and finite element strength subtraction to analyze the stability of the high slope before and after excavation and with supporting. The results provide theoretical support for slope supporting design. |
