单层土地基中静压桩连续贯人的数值模拟

摘要

摘要：在ABAQUS平台上利用位移贯入法，模拟了PHC管桩连续贯入的全过程，求得了贯入时桩侧土体位移变化以及应力变化，研究发现桩土之间的摩擦系数对桩侧土体应力场以及位移场的变化具有重要影响。%The paper adopts the displacement penetration method on ABAQUS platform, simulates the general process for the continuous penetra- tion of the PHC pipe pile, achieves the displacement changes of the pile side soil body and its stress changes, and finds by the research that the friction coefficient between the pile and soil has the important influence on the stress field of the pile side soil body and the changes of the dis- placement field.
