摘要
波形钢腹板PC组合箱梁桥是一种新型结构,由波形钢腹板、体外预应力束、波形钢腹板与上混凝土翼板、下混凝土翼板的抗剪连接件等组成。该文结合2007年以来我国已建成的1座和在建的2座波形钢腹板PC组合箱梁桥,介绍了波形钢腹板组合桥梁的设计要点。为以后类似工程提供了有益的参考。希望能引起桥梁工作者更为广泛的关注,促进该桥型在我国的桥梁建设中得到更加广泛的应用。
The pre-stressed composite box-girder with corrugated steel webs is a new kind of structure, which includes corrugated steel webs, external prestressed cables and shear connectors that connect the corrugated steel webs and the concrete flange slabs. In this paper three pre-stressed composite box-girder bridges with corrugated steel webs in China are introduced from 2007, Design experiences about the bridges are summarized, and their constructions are discussed. It has provided the beneficial reference for the later similar project. More attention should be given to this kind of structure by bridge engineers so that it can be widely used in the bridge engineering in China.
