Influence of intercity railway construction on bridge pile foundation of adjacent high-speed railway

摘要: 高速铁路(简称:高铁)对线路平顺性要求非常严格,邻近高铁的建筑物施工都不可避免地对高铁运营产生影响。文章以某城际铁路桥梁并行高铁及客运专线施工为背景,采用ABAQUS大型有限元软件建立数值分析模型、配设相关参数、进行施工模拟,分析施工对既有铁路桥梁基础的变形响应及桩基内力变化的影响,据此确定并提出预防措施,以规避施工风险确保运营安全。该文可为同类工程的数值仿真模拟和施工提供参考。Abstract: Because of the strict requirement on track fegularity of high-speed railway, the construction of the adjacent building has an inevitable influence on the high-speed railway operation. Taking an intercity railway construction located parallel to the high-speed railway as the study background, a numerical model using software of ABAQUS for large finite element analysis with related parameters setting was established to simulate construction process and analyze the deformation response and axial force effect of existing railway bridge pile foundation. The results could be used to define and implement preventive actions to mitigate identified risks and insure operation safety. This article could provide reference for numerical simulation and construction of similar engineering.
