摘　　要：论述强夯置换法的机理。结合长江某码头工程的饱和软土地基进行的强夯置换试验,证明强夯置换法加固此区域的饱和软土地基是可行的。通过对单点夯击能试验数据的分析研究,获得此区域强夯置换法的最佳强夯参数和施工工艺,并从实践中扩展了强夯法的用途,得出了一些有用的结论。This paper discusses the mechanism of dynamic compaction replacement. According to the example of a harbor project of the Yangtze River, the test of dynamic compaction replacement in ground treatment of saturated and soft soil indicated that it is feasible to adopt dynamic compaction replacement in ground treatment. Based on the analysis of the single-point tamping energy experimental data, we got the best parameters of dynamic compaction and construction technology in this area. Furthermore, we extended the application of DCM and drew some useful conclusions.
