摘要
过往研究常借助数值模拟与现场监测交叉验证的手段,对顶管施工进程中邻近结构所受的动态扰动进行量化解析。文章以实际桥梁工程为背景,针对顶管施工引发的土体扰动对桥梁桩基础的影响展开分析,采用有限元软件模拟顶进过程,探究施工期间土体的变形规律及桩基受力机制,并对比理论计算结果与实测数据,开展安全评估,以期为顶管施工提供参考,保障周边建筑安全。
In the past,numerical simulation and field monitoring cross-validation were often used to quantitatively analyze the dynamic disturbance experienced by adjacent structures during pipe jacking construction.Based on the actual bridge engineering,this paper analyzes the influence of soil disturbance caused by pipe jacking construction on bridge pile foundation,uses the finite element software to simulate the jacking process,and explores the deformation law of soil and the force mechanism of pile foundation during construction.By comparing the theoretical calculation results with the measured data,the safety assessment is carried out,in order to provide reference for pipe jacking construction and ensure the safety of surrounding buildings.
