以湖南省武冈至靖州高速公路工程为依托，针对高速公路路堑边坡开挖方案的边坡开挖参数进行数值模拟，分析各个参数对边坡稳定性影响的规律，并运用正交法得到最优边坡开挖设计方案。结果表明：在一定范围内适当降低平台高度对边坡的安全系数的影响存在3个不同阶段；适当增加边坡平台个数和坡脚处平台宽度能提高边坡的稳定性；并通过正交法解决了实际边坡的边坡开挖优化设计问题。

Based on the highway slop project of Wu-gang to Jing-zhou,numerical simulation meth-ods were proposed for analyzing the rule of various parameters on the slope stability according to the pa-rameters of slope excavation excavation scheme of Expressway Slope,and the orthogonal design method were used for get the optimal design scheme of excavation slope.The results show that:in a certain range, appropriate to reduce the influence of platform height on the slope safety coefficient are three different sta-ges;appropriate increase in slope toe platform number and width of the platform can improve the stability of the slope;and the orthogonal method to solve the actual slope slope excavation optimization design.
