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的机理,并将部分计算结果与量测结果进行比较。The effect of the construction of Guomao Station of Beijing metro line 10 on the adjacent long pile foundation of Guomao Bridge is analyzed by adopting software ABAQUS, and the behavior of pile foundation as well as the mechanism of pilesoil interaction are studied. Partial results acquired by the three - dimensional dynamic simulation are found consistent with those obtained by measurements.
