摘要
为探究基坑开挖对群桩基础水平位移与弯矩的影响,依托具体工程实例,进行有限元数值模拟,确定群桩基础与围护结构参数。根据模拟结果分析基坑开挖对群桩基础水平位移和弯矩的影响,得到基坑施工与群桩基础加载相互影响规律,为相类似工程项目的建设方案制定提供依据。
In order to investigate the impact of excavation on the horizontal displacement and bend‐ing moment of pile foundation,finite element numerical simulation was conducted based on specific en‐gineering examples to determine the parameters of pile foundation and retaining structure.Based on the simulation results,the influence of excavation on the horizontal displacement and bending moment of pile foundation is analyzed,and the mutual influence law between excavation construction and pile foundation loading was obtained,providing a basis for the development of construction plans for simi‐lar engineering projects.
