| 摘 要： | 以沪-蓉国道主干线恩施高坪-吉心段付家坡滑坡地段典型断面为研究对象, 运用强度折减系数法，研究了在天然状态和饱水状态下滑坡体稳定安全系数。 指出了在这两种状态下边坡的不稳定性。并与其他几种方法进行了对比分析，结果表明有限元强度折减系数法应用到该断面是可行的，同时也显示该方法相对于其它方法的优越性。

| Abstract: | Aiming at the typical geological profile of Fujiapo landslide section of Enshi Gaoping—Jixin section in national Hu—Rong highway, the safety factor of the landslide under saturated state and native state are studied using the strength coefficient reduction method of FEM. It is drawn that the slope under those two conditions is unstable. The results have shown that it is feasible to use the FEM of strength coefficient reduction in the above profile and this method has advantages over others. |
