摘　　要：结合北京地铁10号线国贸站西北风道施工对邻近短桩桥基影响这一工程问题,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作了比较。研究成果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。Combined with the Guomao subway station of Beijing metro line NO. 10, by means of ABAQUS software, construction process and construction effect on the adjacent short-pile foundation of Guomao bridge are simulated and the deformation and force character of pile foundation as well as the interaction mechanism of pile-soil are studied. The partial resuits acquired by simulation and measuring are consistent by comparison, and a mass of harvest is achieved. The basis and guidance are provided for the succedent and similar engineering construction.
