上部结构为宽幅现浇箱梁,下部结构采用Y形桥墩,是城市快速路高架桥常见的一种结构布置形式,该形式对下部结构的受力要求较高。本文通过对该类型结构典型Y形桥墩施工过程及运营期受力的有限元分析,分析其受力特性,提出改善建议,并基于分析结果,提出施工过程相应的监控策略,供同类型桥梁设计、施工和建设管理参考。
The upper structure is a wide cast-in-place box girder, and the lower structure is a Y-shaped piers, which is a common structural arrangement of viaducts in urban expressways. This form requires a higher force on the lower structure. In this paper, the finite element analysis of the typical Y-shaped piers construction process and the operation period of this type of structure, analyze the force characteristics, put forward suggestions for improvement, and based on the analysis results, put forward the corresponding monitoring strategy of the construction process for the same type of bridge design , Construction and construction management reference.
