无背索斜拉桥是一种造型优美独特的桥梁结构形式,将具有自重轻、无腹板开裂问题的波形钢腹板PC组合箱梁应用到这种桥型中,形成了波形钢腹板PC组合箱梁无背索部分斜拉桥。以这种新型结构桥梁———溱水路桥为工程背景,对其主塔、斜拉索、箱梁主体、波形钢腹板、连接件、预应力体系布置、施工等方面的设计进行了详细的介绍。
The backless cable-stayed bridge is a kind of beautiful and unique bridge structure. The corrugated steel web PC composite beam with light weight and no web cracking problem is applied to this type of bridge to form a corrugated steel web PC composite box girder part without cable back cable-stayed bridge. Taking this new type of structural bridge --- Baishui Road and Bridge as the engineering background, the design of the main tower, stay cables, main body of box girder, corrugated steel webs, connecting pieces, prestressed system arrangement and construction has been carried out in detail The introduction.
