215 m跨径钢-混凝土混合连续梁桥总体设计

Overall design of 215 m span steel-concrete hybrid continuous beam bridge

本项目桥梁跨径为103 m+215 m+103 m,通过桥型比选,选择钢-混凝土混合连续梁桥设计方案,该桥型方案可充分利用混凝土结构与钢结构两种结构的优势,跨越能力高、经济性好。建立有限元模型对整体及重要局部构造进行验算,对结构设计进行分析。

The span of the project is 103 m+215 m+103 m,compare of different bridge structures,choose the steelconcrete hybrid continuous beam bridge.This structure could use the advantage of concrete structure and steel structure with bigger span and better economies.Establish finite elements model for the overall and important partial structure to analysis the bridge design.
