摘要
以重庆轨道交通九号线隧道下穿城市道路桥台工程为例,通过建立有限元数值模型,计算分析了隧道开挖、桥基及桥台的变形发展规律,并探讨了轨道施工对桥梁结构的影响,为下阶段隧道设计和施工提供依据。
Taking the road abutment engineering of Chongqing rail transit line 9 tunnel underground city as an example,through the establishment of finite element model,calculated and analyzed the deformation and development laws of tunnel excavation,bridge foundation and abutment,and discussed the influence of rail construction to bridge structure,provided basis for the next phase tunnel design and construction.
