摘　　要： 以广州某软土地基工程为例,介绍了一种采用堆载预压与强夯法联合处理软土地基的施工技术,包括施工工艺流程,排水系统设置及强夯施工过程。使用ADINA有限元软件对该软土地基处理的施工过程进行模拟分析,为施工参数选定提供参考。模拟计算的工后沉降及工后现场监测结果表明:联合采用堆载预压与强夯法处理该区域内的饱和淤泥质砂土软土地基场地效果良好。 Based on a soft soil foundation in Guangzhou, this paper introduced a new pre-compression method by pre-loading and dynamic compaction including its construction process, drainage system and dynamic compaction construction process. ADINA was used to analyze the construction process of this method in order to provide reference for choosing construction parameters. Through comparative analyzing the post settlement of this project by FEM and the measured post settlement, it shows that the excellent engineering effect is achieved by the pre-eompression with pre-loading and dynamic compaction.
