| 中文摘要:结合柳州市柳东新区物流港片区在建道路的边坡支护工程实例，分析由于道路工程的路堑设计施工造成的高差约35 m高边坡，基于极限平衡理论的Bishop条分法理论分析，使用理正岩土设计软件对边坡进行滑动面选择，并进行稳定性分析及剩余下滑力计算，探讨锚索桩-墙复合垂直抗滑结构的设计思路；通过承载力极限条件对桩的截面尺寸和配筋进行复合；同时介绍垂直支护结构以上边坡坡面处理、防护、排水方案；为今后在道路工程造成的高边坡类支护、治理工程提供参考。 |

| Abstract:This paper discusses the design approach for the vertical anti slide structure of the anchor cable and pile wall combination through theoretical analysis of the Bishop strip method based on limit equilibrium theory， selection of the sliding surface of the slope by use of the Lizheng Rock Soil design software and stability analysis and calculation of the residual down sliding force in the context of the slope support project for a road under construction in the logistics port area of Liudong New District of Liuzhou City， where the elevation difference of the slope caused by the design and construction of road cutting is about 35m high. Combination of the pile cross section size and re bars is conducted under the bearing capacity limit conditions; meanwhile， the slope surface treatment， protection and drainage scheme above the vertical support structure are also introduced. It may provide reference for the high slope support and treatment projects in road construction in the future |
