摘　　要：土工格栅加筋柔性支护技术已成功处治广西南宁至友谊关、百色至隆林以及北京西六环高速公路膨胀土路堑边坡的坍滑问题,文章结合该技术在南北方膨胀岩(土)堑坡的应用实例,对两地不同膨胀岩(土)工程地质性质、边坡破坏形式及特定设计方案进行了对比分析,得出实施该技术的普遍有效性,同时提出必须因地制宜根据实际工况不断地对该技术方案作出相应补充、修改与完善,以真正经济有效地解决不同地域及类型膨胀岩(土)路基"逢堑必滑"的技术难题。The geogdd reinforced flexible support technology has successfully dealt with the slump problem of expansive soil cutting slope in Guangxi Nanning-Friendship Gate, Baise-Longlin and Beijing West Sixth Ring Expressway,thus, combined with the application practices of this technology in the expansion rock（soil）cutting slope in the south and north,this article conducted the comparative analysis on engineering geology, slope failure forms and specific design scheme of different expansive rock（soil）in different places,obtained the general validity of implementing this technology,and at the same time, it proposed that this technical program requires the corresponding supplement, modification and improvement according to the actual construction conditions and based on real geology,so as to find the truly cost-effective solution to＂collapse of every cutting-slope＂technical problems of different types of expansion rock（soil）subgrade in different regions.
