| 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这一实际工程问题，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19-3号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，取得了一系列的成果。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。

| Abstract: | Combined with the Guomao Subway Station on Beijing metro line 10, by means of ABAQUS software, construction process and construction effect on adjacent 19-3 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 results acquired by simulation and measure are consistent by compare and a mass of harvest is achieved. The conclusions are reached that 19-3 pile foundation 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. |
