摘要
为了提高静压沉桩模拟的计算效率,同时改善网格的形态提高计算精度,利用ABAQUS/Explicit和ALE方法实现了对静力压桩的全过程的准静态分析。并且对沉桩的总阻力进行了敏感性分析,研究了桩土摩擦系数、土体的弹性模量和内摩擦角对不同贯入深度沉桩总阻力的影响。研究结果有助于增强对沉桩总阻力和桩基承载力的理解。
In order to improve the computing efficiency of the simulation for jacked piles andto improve the shape of the deformed mesh which has a significant influence on the calculation accuracy,ABAQUS / Explicit module and ALE adaptive meshing are used to achieve the quasi- static analysis of penetrating jacked piles. Meanwhile,a sensitivity analysis is performed onpile- soil friction,the elastic modulus and internal friction angle of the soil.
