摘　　要：结合工程实例系统论证了夯扩碎石桩在沿湖临空面深厚层软土地基上处理高填方城市主干路已滑坡段的方案布置。为了满足边坡稳定及沉降要求,论证比选了抗滑桩、强夯置换墩和夯扩碎石桩三者之间在工程上的优劣性,采用了夯扩碎石桩复合地基。通过荷载试验及位移观测等成果分析,复合地基满足工程抗滑稳定要求。Combined with the engineering cases,the article systematically demonstrates the scheme of rammed gravel pile to treat the landslide section of the high-filled urban trunk road at the free surface of deep soft soil foundation along lake.In order to meet the slope stability and settlement requirements,the article demonstrates and compares the superiorities and inferiorities of anti-slide pile,dynamic replacement pier and rammed gravel pile in the engineering construction.The rammed gravel pile compound foundation is used.According to the result analysis of load test and displacement observation,the compound foundation can meet the engineering anti-slide stability requirements.
