摘要

运用透水管桩技术加快沉桩后桩周土体内超静孔隙水释放，进而消除沉桩施工中超静孔压的不利影响。基于有限元数值计算法，利用ABAQUS有限元软件建立透水管桩模型，实现透水管桩贯入过程以及桩周土体固结过程模拟。对比CEM圆柱孔扩张理论验证数值计算结果；阐述透水管桩贯入过程中位移场以及超静孔压场变化规律；对比分析静压桩和透水管桩桩周土体固结性状，结果表明透水管桩能加速超静孔压消散，短期内实现桩基承载力的快速提升。

Abstract

The dissipation process of excess pore water pressure could be spread out by using permeable pipe pile. Furthermore

the negative effects in pile driving could also be eliminated. Based on FEM and the permeable pipe pile calculation model built by ABAQUS finite software

the simulation of permeable pipe pile penetration and soil consolidation could be realized. Throughout the experiment

the numerical results are validated by contrasting CEM. Meanwhile

the variations of displacement field and excess pore pressure field created in permeable pipe pile penetration process were clearly described. Compared soil consolidation around static pressure pile and permeable pipe pile

it is shown that permeable pipe pile could accelerate excess pore water to dissipate and achieve a significant promotion of pile bearing capacity in a short time.
