摘　　要：动力排水固结法具有施工易、速度快、成本低等优点,但在设计和施工上仍处于探索阶段。为减少场地的工后沉降,采用动力排水固结处理珠三角某沿海工程的深厚软基,并取得良好效果。依据现场的监测检测结果,讨论其作用机理,并与堆载预压进行对比,总结了若干设计原则,提出夯能拟定及排水垫层保护的方法,供类似工程参考。Dynamic consolidation has the advantages of easy construction,high speed and low cost,but it is still in the exploratory stage in design and construction.In order to reduce the settlement after construction of the site,dynamic consolidation was used to treat the deep soft foundation of a coastal project in the Pearl River Delta,and good effect was achieved.Based on the field monitoring results,its mechanism was discussed.Comparing with preloading,some design principles were summarized,and the methods of determining the tamping-energy and the drainage-cushion-protection were put forward for reference in similar projects.

关 键 词：动力排水固结 软基处理 夯能拟定 土工材料对排水垫层的保护
