摘　　要：以阿尔及利亚东西高速公路为例,介绍了在泥灰岩地区对出现滑移趋势的边坡和路基采用挡土墙处治的技术。对处理后的路基、边坡采用Bishop圆弧滑动法进行整体稳定性分析,分析结果能满足设计要求。通过竣工通车后几个雨季的观察,边坡、路基整体性稳定。Taking Algeria East-West Highway for example, with sliding trend in marlite area treated with retaining wall the treated subgrade and slope are separately analyzed using satisfy design requirement. Through observation for several that slope and subgrade are basically stable. the control technology for the slope and subgrade is introduced in this paper. Then the stability of Bishop circular sliding method and the results can rainy seasons after opening to traffic, it is shown
