摘　　要：为了研究桩基加载对高架桥结构的力学响应以及变形规律,文中采用ABAQUS仿真施工软件对高架桥结构桩基加载施工作业进行模拟,并对不同工况下桩基施工对高架桥稳定性进行分析。并以青岛东岸产业园区高架桥建设项目为依托,将现场监测数据与文中模拟施工数据对比,结果表明:现场监测数据与数值模拟结果趋势相同、位移差异不大,验证了文中方法的准确性,为地铁施工稳定性分析提供了一种新的方法。In order to study the mechanical response and deformation law of the viaduct structure under pile foundation loading,the ABAQUS simulation needle construction software was used to simulate the pile foundation loading construction operation of the viaduct structure,and the stability of the viaduct under different working conditions was analyzed.Based on the viaduct construction project in Qingdao East Bank Industrial Park,the on-site monitoring data was compared with the simulated construction data in the article.The results showed that the trend of the on-site monitoring data was the same as that of the numerical simulation results,and the displacement difference was not significant,which verified the accuracy of the method in the article and provided a new method for the stability analysis of subway construction.
