| 摘 要： | 依托贵州省某高速公路陡坡填方路堤滑坡治理工程，对已竣工路肩墙在路基滑坡牵引下破坏垮塌的实际问题，在路肩位置采用仰斜式路肩墙与抗滑桩联合支挡结构进行治理；运用FLAC3D对桩墙联合支挡结构进行计算，分析治理后的边坡变形沉降、稳定性及其各部分受力特点。治理效果表明：桩墙联合支挡结构治理后边坡稳定性较好，变形、裂缝均在设计控制范围内。

Application of Pile-Wall Combined Retaining Structure in Treatment of Steep Slope Filled Landslide |
| |
| Abstract: | Based on a highway of Guizhou province for landslide of steep slope embankment, with respect to the issue of completed shoulder wall collapse under subgrade landslide destruction, the back inclined type shoulder with anti-slide retaining wall structure have been adopted at the shoulder position, and the FLAC3D has been used to carry out calculation analysis of the combined retaining structure. The deformation, settlement, stability and stress characteristics of each part of the slope after treatment have been analyzed. The tretment effect shows the slope stability is good after treatment of pile-wall combined retaining structure, and the deformation and cracks are within the design control range, |
