摘　　要：在现场试验的基础上,对采用强夯法处理可液化地基过程中的有关单点夯击能和有效加固深度、最佳夯击能和夯击次数、夯击遍数和时间间隔、夯点距及夯点布置等强夯参数进行了理论分析,给出了这些强夯参数的基本计算公式和设计方法。其结论可以为设计施工提供参考。Dynamic compaction method is very efficient for liquefiable ground treatment. Based on field test, the DCM parameters during liquefiable ground treatment by dynamic consolidation such as temping energy, efficient consolidation depth, temping frequency, time interval and distance between two tamping, arrangement of tamping location are analyzed. The calculation formula and design method of these parameters are obtained. The conclusions can guide the design and construction of DCM.
