边坡土体内渗流场与应力场是相互作用、相互影响的一个整体。针对地下水渗流对边坡稳定性的影响,文章开展渗流场与应力场相互作用机理的研究,并利用ABAQUS有限元软件进行建模分析,验证有限元强度折减法及其失稳判据在边坡稳定分析中的可靠性及合理性。结果表明：地下水渗流作用影响下的边坡稳定性明显降低,安全系数由未考虑渗流作用时的1.33降至1.097,边坡发生失稳破坏,地下水渗流是影响边坡稳定的重要因素。

The seepage field and stress field in slope soil are a whole that interact and influence each other.In view of the influence of groundwater seepage on slope stability,this article studied the interaction mechanism between seepage field and stress field,and used ABAQUS finite element software for modeling analysis,it verified the reliability and rationality of FEM strength reduction method and its instability criterion on the slope stability analysis.The results showed that the slope stability under the influence of groundwater seepage is significantly reduced,the safety factor is reduced from ...
