摘　　要：有限元强度折减法是近些年来发展起来的一种边坡稳定性评价方法,采用有限元强度折减法,对武黄城际铁路谈山隧道进口高边坡进行稳定性分析,分析结果表明高边坡整体稳定,仅需对边坡坡面进行修整,并对松动小石块加以防护即可。Finite element strength reduction method is a method evaluating slope stability developed in recem years. With this method, the stability of the high slope at Tanshan Tunnel entrance on Wuhuang Interurban Railway is analyzed. The result shows that the high slope is stable as a whole and only the surface needs to be trimmed with protection against some loose small stones.
