新密市溱水路大桥波形钢腹板无背索斜拉桥总体设计

在桥型方案确定后，桥梁总体设计是设计者首先考虑的问题．新密市溱水路大桥波形钢腹板无背索斜拉桥的总体设计研究了桥梁结构受力特点，初拟了桥梁主要结构组成，对主体结构进行了初步的结构计算分析，并得出了初算成果，确认了桥型方案的可行性和结构的合理性．在该桥设计中，首次将波形钢腹板箱梁应用于无背索斜拉桥结构，为波形钢腹板箱梁组合结构在我国的推广应用奠定了基础．

Design for Corrugated Steel Webs Cable-stayed Bridge without Backstays of Zhenshuilu Bridge in Xinmi

After the scheme of bridge is determined,the design of bridge is the first problem considered. The design and calculation resuits for corrugated steel webs cable-stayed bridge without backstays of Zhenshuilu bridge in Xinmi were introduced. The characteristics of the structures of the bridge with loads were studied, the compostiton of the main structures of the bridge was determined, the main structures were preliminarily calculated and analyzed, and the results were got, the feasibility and the rationality about this brige＇s design scheme were proved. In this bridge＇s design, box girder with corrugated steel webs was firstly applied to the structure of cable-stayed bridge without backstays,this takes a new step for the application of box girder with corrugated steel webs of composition structures in China.
