近年来,强夯置换墩法以其工期短、施工简单等特点在软基工程中得到了越来越广泛的应用.但由于对其加固机制的研究还不是很深入,理论研究远远滞后于工程实践,难以建立起符合强夯碎(块)石墩特点的设计理论和方法.为此针对海满高速公路实际工程,结合有限元分析,对该方法处理湿地软基的加固机制进行了深入研究,其结果可供施工设计人员参考.

In recent years, the dynamic compaction replacement (DCR) is widely used to consolidate soft soil foundation for its short period and simple construction and so on. But the reinforcement mechanism of DCR hasn't been well researched; theoretical study is far behind engineering practice; so it is hard to build up the design theory and method. Based on the Haiman expressway project in wetland and by using the finite element method, the mechanism of DCR reinforcing expressway soft roadbed in wetland is studied so as to give some reference to designers.
