上海哥白尼路川杨河梁拱组合桥设计与研究

Design&Research of Chuanyanghe Beam Arch Composite Bridge on Gebaini Road,Shanghai

哥白尼路川杨河桥位于上海浦东张江高科技园区,跨越川杨河。受规划用地及两岸道路的制约,主桥梁高受限。设计方案采用侧向悬挂多重梁拱组合体系,较好解决了城市桥梁建设中经常遇到的车行和人非过河问题。采用有限元软件进行静力、动力分析及关键部位的精细化分析,验证了结构可靠性;提出“纵向悬浇+横向拼装”的施工工艺,实现了施工快速化和桥梁构件的轻型化。该桥型为国内首次应用,可对设计和施工起到指导作用,为城市桥梁建设提供参考。

The Gebaini Road-Chuanyang River Bridge is located in the Zhangjiang Hi-Tech Park in Pudong,Shanghai,spanning the Chuanyang River.Due to the constraints of planned land use and roads on both sides,the height of the main bridge is limited.The design scheme adopts a lateral suspension multiple beam arch combination system,which better solves the problems of vehicle and pedestrian crossing the river often encountered in urban bridge construction.Finite element software is used for static and dynamic analysis and refined analysis of key parts to verify the structural reliability.The construction process of longitudinal suspension casting+lateral assembly is proposed to achieve rapid construction and lightweight bridge components.This bridge type is the first application in China,which can guide design and construction,providing a reference for urban bridge construction.
