考虑渗流作用下某路基边坡稳定性分析

STABILITY ANALYSIS OF SUBGRADE SLOPE UNDER THE ACTION OF SEEPAGE

由于山区工程地质条件较复杂,在公路建设中时常遇到填方边坡与挖方边坡。路基边坡稳定性问题是山区公路工程中非常重要的研究课题,其稳定性直接影响到公路的施工与运行安全。路基边坡的稳定性在很大程度上受到渗流作用的影响,因此,在渗流作用下的路基边坡稳定性问题研究显得尤为重要。本文采用理论与数值模拟相结合的方法,利用Midas/GTS软件对某山区路基边坡进行渗流作用下的稳定性研究。分析表明,边坡目前处于稳定状态,在路基两侧边坡坡面中部均出现位移与剪应变较大区域,且渗流主要集中在全风化砂岩中,应针对潜在的稳定性问题进行相应加固措施。

Because the mountain engineering geological condition is complex, we often encounter the embankment slope and excavation slopes in highway construction. very important research project in mountainous area highway engin Subgrade slope stability problem is a eering. Its stability directly affects the safety of highway construction and operation. The stability of the subgrade slope is influenced by the seepage flow. Therefore, the research on the stability of the subgrade slope under the influence of seepage is very important. In this paper, the stability of the subgrade slope in a mountainous area is studied by using Midas/GTS software. Analysis shows that the slope is in stable condition at present, and there is a large area of shear strain on both sides of the subgrade, and the corresponding reinforcement measures should be carried out according to the potential stability.
