摘　　要：结合北京地铁10号线国贸站转弯段施工对邻近桥基影响的实际工程问题,运用ABAQUS软件,在对施工过程进行动态模拟的同时,重点研究了施工过程中19-1号桥基的变形和受力性态以及桩-土相互作用机制,并将部分计算结果与量测结果进行了比较。研究表明,施工期间桥基没有工程安全隐患,既有的施工方案是合理、可行的,并为该工程的施工提供了依据,也可供类似工程参考。In light of the Guomao Metro Station of Beijing Metro line 10,and using ABAQUS software,the construction process and construction effect on the adjacent pile foundation19-1 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 results acquired by simulation and measurement are compared;and a mass of harvest is achieved.The conclusions are reached that pile foundation19-1 of Guomao Bridge is safe during construction;and existing construction;project is reliable.The basis and guidance are provided for succedent Guomao Metro Station and similar engineering construction.
