摘要
通过深入研究饱和土体中自由水运动机制,以湖南省长张高速公路K254右边坡断面为依托工程,基于Midas/GTS数值分析平台,对无渗流情况的顺层边坡的稳定性进行了对比研究,通过二者对比,定量地分析了渗流对顺层边坡体的位移与应变的影响,得了一些有益的结论,并引入强度折减法对两种情况下边坡的稳定性安全系数进行了比较,以期为实际工程提供一定的理论指导。
Through analyzing the movement characteristics of freedom water in the saturated soil,the right K254 slope cross-section in Chang-zhang Highway is employed to investigate the influences of the no-seepage and seepage on the stability of bedding slope based on the numerical software Midas /GTS,respectively. By making a mass of comparison between the two cases of no-seepage and seepage,some conclusions about the characteristics of displacement of slope under the seepage are obtained.Meanwhile,the strength reduction FEM are introduced to study and compare the safety factors of the slope under no-seepage and seepage. The obtained conclusions in this paper can provide references for the practical engineering.
