摘要
基于欧拉-拉格朗日耦合(CEL)分析方法,运用ABAQUS有限元软件对移动式平台的插桩过程进行数值模拟。通过分析不同土壤条件和插桩速度对于插桩阻力的影响,得出当土壤的不排水抗剪强度越大时,插桩阻力随着插桩深度变化的曲线振荡越明显;当插桩速度越大时,插桩阻力越大,并且拐点出现的越慢。
Based on CEL analysis method,the pile insertion process of mobile platform is numerically simulated by ABAQUS finite element software.By analyzing the influence of different soil conditions and pile insertion speed on the resistance of pile insertion,it is concluded that the greater the undrained shear strength of the soil,the more obviously the curve of insertion resistance oscillates with the depth of the pile;and the higher the insertion speed,the greater the pile insertion resistance is and the more slowly the infection point appears.
