摘　　要：填海造地过程形成的冲填土地基,其地下水位较高,承载力低,采用降水联合强夯法施工工艺,有效地解决了大面积地基处理的问题。通过对两种常用降水方法的理论及试夯效果的分析,从技术、经济及施工适宜性各方面进行了阐述,为降水联合强夯法中科学合理选用降水工艺提供了参考。The bearing capacity is low and the ground water level is high of the hydraulic filling foundation which formed by the process of the marine reclamation land. Dewatering combined dynamic compaction ground treatment method can solve the problem of the lagrer area foundation treatment. Based on the theoretical and trial tamping results analysis in different dewatering methods, the technical, economic and construction suitability are expounded. And one scientific and rational choice dewatering method will be selected.
