摘要
吉茶高速公路坡头隧道仰坡高达70余m,采用1∶0.3以及垂直坡比。采用抗剪强度折减系数法,计算不加锚索、加锚索两种情况下的仰坡稳定性,可为山区高速公路类似的边仰坡设计与施工提供参考。
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.
