| 摘 要： | 选取包括溢洪道冲刷坑在内的马崖高边坡的典型地段，为研究溢洪道泄洪冲刷对未整治和削坡整治后的马崖高边坡稳定性的影响，进行了三维弹塑性有限元分析。结果表明泄洪冲刷将引起马崖的上部边坡朝坡外且向下变形，削坡整治后的边坡其变形和塑性屈服区均较未整治时小。

| Abstract: | Taking a typical section of Maya high slope including the scour hole of the spillway,3D elasticoplastic finite element analyses on the influences of flood scouring of the spillway upon stabilities of Maya high slope(treated and untreated) were performed.The calculation results showed that the flood scouring will cause downward and outward deformation of the super part of Maya high slope,but after cutting part of the sliding mass the size of the deformation and the plastic yield zone would be smaller than that without treatment. |

| Keywords: | high slope flood scouring elastic plastic behavior stability finite element |
