| 摘 要： | 为深化研究岸坡被动桩的承载特性,运用国际大型通用有限元软件ABAQUS对岸坡被动桩进行三维模拟。研究发现,坡顶荷载是被动桩桩身位移与桩身弯矩的主要影响因素,桩身位移与桩身弯矩随着破顶荷载的增大而增大;坡顶荷载对桩身弯矩的影响主要集中在斜坡范围内;桩顶荷载对减小桩身弯矩有利。结果表明,基于ABAQUS的三维有限元模拟是研究岸坡被动桩的有效方法。

| Abstract: | To deepen the study of bearing characteristics of slope passive piles, based on the international general-purpose finite element software ABAQUS, this paper carries out a 3D simulation of slope passive pile. It is found that: The peak load is the main factor of pile displacement and pile bending moment, pile displacement and pile bending moment increase with the increment of the peak load; The influences of the peak load on the pile bending moment is mainly within the slope. The load on the pile top is favorable to reduce the pile shaft moment. The conclusion can be drawn that the ABAQUS finite element simulation is an effective method for studying the bearing behaviors of passive piles of bank slopes. |
