摘　　要：针对围海造地形成的软弱地基,提出了间接分级接力式排水固结法。该方法通过构建转换层,建立间接分级接力式排水体系,利用上部堆载及强夯动力促进下部饱和黏性土层排水固结。本文介绍了该方法的基本原理并结合具体试验,证明了该工法较普通降水强夯法对下部饱和黏性土层处理效果更好,且具有一定的工期优势。A new sort of treatment technology,combinational-ordered drainage consolidation method,has been innovated for the soft foundation in the reclaiming land from the sea. The method builds the transfer layer to establish the combinational-ordered drainage system and combines upper loading and dynamic compaction to contribute to the lower saturated clay＇s consolidation. In this paper,the method＇s principle is introduced and it is proved that it works better in reinforcing the lower saturated clay than the general dynamic compaction method.Besides,the method has some advantage over the general dynamic compaction method on shortening the construction period.
