摘要
本文对于锤击法沉桩过程进行了弹塑性有限元动力分析。计算结果表明:动力分析得出的贯入度大小及变化规律与实践经验吻合良好。作者利用有限元计算的结果,给出了计算区域内超静孔隙水压力及塑性区的分布图形,通过初步的讨论得出了有益的结论。
In the paper, we discuss the result of elastic - plastic FEM dynamic analysis of pile driving. Comparison is carried out between FEM results and those calculated by Hiley formula. It is found that the deformation of pile driving are similar between the two methods. The results of FEM show the distribution of excess pore pressure and plastic zone. At last, we discuss many factors which should be considered in the pile driving.
