某集装箱码头强夯处理有限元分析

Finite element analysis of dynamic compaction in foundation treatment of a container terminal wharf

根据某集装箱码头勘测资料,采用拟静力方法,建立三维有限元模型。分析了强夯处理下地基位移和孔隙水压力的变化规律,得出了夯坑沉降量与夯击数之间的关系,经与现场实测结果对比表明数值模拟效果较好,数值模拟能够反映强夯施工中的各种现象,可为强夯施工设计服务。

Three-dimensional finite element analysis model was built by the quasi-static force method on the basis of data of a container terminal wharf. The ground was consolidated by dynamic compaction method, the variety rules between the number of tamping passes and the crater settlement were confirmed by analysis of ground deformation and pore pressure. The numerical simulation results of dynamic compaction show that the simulation results are in accord with the field test results on the whole, the numerical simulation can explain all kinds of phenomenon and can serve for construction design of dynamic compaction.
