| 摘 要： | 基于ANSYS软件分析了桩土之间的相互作用，模拟了桩打入时土中的应力、应变情况。通过结合ANSYS中的接触分析和生死单元，以DP材料来模拟土体，采用循环命令的方式来分析桩土接触时复杂的应力状态。模拟结果得到了圆孔扩张理论和极限平衡法的验证。

| Abstract: | The interaction of soil and pile is analyzed by ANSYS; and the state of stress and strain in the soil after the pile was driven in is simulated. By combining the contact analysis with birth - death element of ANSYS, and proposed the soil material comply with the Drucker-Prager criterion, the circulation command is used to analyze complicated soil stress state. These results are verified by limit equilibrium method and theory of expansion of a cavity. |
