| Abstract: | The front slope of Potou Tunnel on Jishou to Chadong Expressway is around 70 meters high with a vertical slope ratio of 1：0.3.In this paper,the slope stability has been computed on the conditions with anchor cable or without anchor cable by adopting the method of Shear Strength Reduction Factor.It can provide some reference for the design and construction of similar front slopes of highway tunnels in mountainous areas. |
