摘　　要：以四川省某高填方边坡项目为例,结合手算及理正岩土设计软件,对加筋土柔性结构在边坡治理及其地基处理过程中的应用进行研究。结果表明,通过边坡未加筋时设计安全系数对应的包络线能更好的确定加筋区域;采用格宾石笼处理加筋土边坡填土地基,减小了软弱下卧层的沉降量。研究数据与结果,可为类似工程提供参考和建议。This paper presents an application of reinforced flexible structure in a high fill embankment in Sichuan Province.The performance of the reinforced soil slope was analyzed by Lizhen commercial software and hand calculations.The results indicate that the slip surface of the unreinforced zone before adding the reinforcement can be used as the bases of determining the reinforcement length.Gabion basket treated slope reduces the potential settlement of the fill soils.
