摘　　要：因软土地基比较特殊,导致软土地基上侧的道路出现失稳、路基不均匀沉降的可能性非常大。论文以某高速公路建设项目作为研究案例,对袋装砂井法进行研究分析,简单介绍了袋装砂井加固方法的基本原理,并根据实际施工状况提出有效的质量管控措施。结合路堤回填以后的沉降观测结果来看,袋装砂井加固技术具备良好的技术可行性,且该技术的经济效益较为显著,可以在大范围内进行宣传推广。Because soft soil foundation is special,it is very possible to make the road on the upper side of soft soil foundation unstable and subgrade uneven settlement.This study takes an expressway construction project as a case study,studies and analyzes the bagged sand well method,briefly introduces the basic principle of this reinforcement method,and puts forward effective quality control measures according to the actual construction situation.Combined with the settlement observation results after embankment backfilling,it can be seen that the bagged sand well reinforcement technology has good technical feasibility,and the economic benefits of this technology are relatively significant,and it can be popularized in a large range.
