摘要

基于浙江某光伏工程的现场静载试验

利用ABAQUS有限元软件建立使用混凝土塑性损伤（CDP）模型的预应力高强混凝土（PHC）竹节桩三维数值模型

分析了竹节直径、竹节间距和竖向荷载对水平承载性能影响。研究表明：桩身弯矩主要集中在地面以下0~10d（d为桩身直径）的范围

桩身最大弯矩出现在地面以下3.5d~5.0d处

且随水平荷载增大而下移;竹节直径不大于1.5d时

竹节直径每增加10%

水平承载性能约上升3%;竹节间距小于5.0d有助于保持优良的承载性能

小直径桩设置竹节间距为1 m是较为合理的;竖向荷载增大到其设计值可提高水平承载力18%。

Abstract

Based on field static load tests from a photovoltaic project in Zhejiang

a three-dimensional numerical model of prestressed high-strength concrete （PHC） nodular piles are established using ABAQUS finite element software

incorporating the concrete damaged plasticity （CDP） model. The study analyzes the effects of nodular diameter

spacing between nodules

and vertical load on their lateral load-bearing performance. The findings reveal that the bending moment of the pile body is mainly concentrated within the range of 0~10 pile diameters （d） below ground level

with the maximum bending moment occurring at 3.5d~5.0d below the surface

and progressively shifting downward as the horizontal load increases. The nodular diameter not exceeding 1.5d

with each 10% increase

enhances lateral load-bearing capacity by approximately 3%. Spacings less than 5d between nodules are conducive to sustaining superior load-bearing performance

with a 1 m nodular spacing for smaller diameter piles deemed optimal. Elevating the vertical load to its designed capacity augments horizontal load-bearing ability by 18%.
