摘　　要：测试了布袋桩复合地基与旋喷桩复合地基深层沉降和路基边缘的深层水平位移。通过2种复合地基深层沉降和水平位移的对比分析,对布袋桩复合地基的加固效果进行了探讨。研究表明:采用布袋注浆桩复合地基方案,其技术效果与旋喷桩复合地基相近,但具有更高的性价比。The deep subsidence as well as deep horizontal displacement of bag-grouting-pile composite foundation and high-pressure-jet-grouting pile composite foundation is tested.Through the contrast of the two ways,It further discuses the reinforcing effect of bag-grouting-pile technique.The research comes to this conclusion:the bag-grouting-pile maintains similar technical effects to that of high-pressure-jetgrouting-pile,but achieves higher performance-cost ratio.
