摘　　要：文章基于四川某高速公路沿线的实地踏勘调研和实测数据,采用Ansys软件建立沿线松散堆积体填料边坡数值模型,分析了堆积体填料高度、顶部平台宽度、坡度等影响松散堆积体堆积稳定的因素。通过改变填料边坡单边高度和坡度等参数,对堆积坡体的安全系数、内部应力和堆积体坡脚位移进行模拟分析。结果表明,采用边坡分级施工的方式可以有效提高松散堆积体填料边坡稳定性,下部边坡坡度参数变化对于填料边坡稳定性具有决定性的作用。Based on the field investigation and measured data along an expressway in Sichuan Province,this paper uses Ansys software to establish a numerical model of loose accumulation filling slope along the expressway,and analyzes the factors affecting the stability of loose accumulation such as the height of accumulation filling,the width of top platform and slope.By changing the parameters such as the unilateral height and slope of the filling slope,the safety factor,internal stress and slope toe displacement of the accumulation slope are simulated and analyzed.The results show that the slope grading construction method can effectively improve the stability of the loose accumulation filling slope,and the change of the lower slope parameters plays a decisive role in the stability of the filling slope.
