摘　　要：为研究强风化砾岩区取土场开挖后边坡稳定性,本文依托实体工程,采用FLAC 3D数值模拟软件建立取土场计算模型,研究甘肃某取土场开挖前后边坡水平位移、应力场分布及稳定性。结果表明:边坡开挖后,一般工况、降雨工况及地震工况下边坡均出现水平位移且地震工况作用下的位移扩展区域最大;边坡开挖后边坡坡脚应力场分布发生明显突变。In order to study the stability of the slope after the completion of the excavation site in the strongly weathered conglomerate area,this paper relies on solid engineering and uses FLAC 3D numerical simulation software to establish a calculation model of earth extraction field,to study the horizontal displacement,stress field distribution and stability of slope before and after excavation of an earth extraction field in Gansu.The results show that:after excavation of slope,horizontal displacement occurs on the slope under general working conditions,rainfall conditions,and earthquake conditions,and the displacement expansion area is the largest under seismic conditions.And the distribution of the stress field at the foot of the slope after the excavation of the slope changed obviously.
