摘要:
基于ABAQUS有限元仿真平台，建立精细化桩—土相互作用模型，结合地应力平衡与显式动力分析方法，系统研究了不同抱夹器安装高度及材料属性（Q345与Q235）对土体能量传递效率的影响规律。结果表明：降低抱夹器安装高度可缩短应力波传播路径，优化能量传递方向性，从而提高传递效率；由于Q345与Q235的弹性模量相近，土体内能分布差异较小，但Q345较高的屈服强度可抑制抱夹器局部塑性变形，减少能量损耗，使其土体有效传递能量略高于Q235；与顶锤式方法相比，抱夹式锤击桩因缩短桩内传播路径而具有更高的能量传递效率，当抱夹器安装在桩身高度的1/4位置时，其效率与顶锤式方法相近。研究成果可为新型抱夹式锤击桩施工工艺优化与设备设计提供参考。
Abstract:
Based on the finite element simulation platform ABAQUS, a refined pile-soil interaction model was es‐tablished. Combined with the in-situ stress balance and explicit dynamic analysis method, the influence of clamp in‐stallation heights and material properties（Q345 and Q235）on the energy transfer efficiency in soil were systemati‐cally studied. The results indicate that reducing the installation height of the clamp can shorten the propagation path of stress wave, optimize the directionality of energy transfer, and thus improve the transfer efficiency. Since Q345 and Q235 steel have similar elastic moduli, the difference of energy distribution in soil is small. However, the higher yield strength of Q345 can inhibit local plastic deformation of the clamp and reduce the energy loss, so that the effec‐tive energy transfer of soil is slightly higher than that of Q235. Compared with the top-hammer driving method, the clamp-type hammer pile driving exhibits higher energy transfer efficiency due to the shortened propagation path within the pile, and when the clamp is installed at one-quarter of the pile height, the efficiency is comparable to that of the top-hammer method. These findings can provide reference for the construction process optimization and equip‐ment design of the novel clamp-type hammer pile driving method.
