摘要
结合北京地铁10号线国贸站西北风道施工对邻近中长桩桥基影响的这一工程问题,运用ABAQUS软件,在对施工过程进行三维动态模拟的同时,重点研究了施工过程中这类桥基的变形和受力性态以及桩土相互作用机理,并将部分计算结果与量测结果进行了比较。研究表明,施工期间桥基的最大沉降值为12.35mm,能够满足其沉降控制标准,现有的施工方案是合理可行的,为该工程施工提供了决策和指导作用,也可供类似工程参考。
Based on an engineering problem of the ventilation tunnel of Beijing Subway Line No. 10 Guomao Station impacting foundation of neighboring bridge, we utilize 3D Dynamic View to simulate the construction process with ABAQUS software, and make the key study on distortion and force form and soil -pile interaction to the bridge foundation, and also compared-the two results of calculation and measurement. The study shows that the maximal sedimentation value is 12.35 mm which can fit for the standard of sedimentation control, so the construction scheme is reasonable and feasible.
