摘　　要：通过分析广州软土地基的特点和地基综合处理的要求,结合现场动力排水固结试验和效果比较,探讨动力排水固结法处理软土-松砂双层软弱地基的原理,研究动力排水固结法在处理软土-松砂双层软弱地基时设计施工参数的选取要求。研究表明正确选择动力排水固结法的设计施工参数,可有效加固软土和其下的松砂。The characteristics of soft clay foundation in Guangzhou are studied and the request of foundation treatment is analyzed. By field test of dynamic and drain consolidation method and its effect comparison, the mechanism and the designed construction parameter of dynamic and drain consolidation method in treating clay and loose sand double weak layers foundation are discussed. The study indicates that by selecting the right designed construction parameter of dynamic and drain consolidation method, soft clay layer and loose sand layer below are strengthened efficiently.
