波形钢腹板箱梁所具有的、区别于普通混凝土箱梁的独特特征主要表现在采用波形钢腹板,体外预应力束,波形钢腹板与上、下混凝土板的抗剪连接件等3个方面。我国一些单位对波形钢腹板PC组合箱梁结构的力学性能展开了研究,取得了重要的进展。本文介绍我国在建的2座以及建成的2座波形钢腹板PC组合箱梁桥,并对该桥型在我国的应用发展前景进行了探讨,希望能引起更为广泛的关注,促进该桥型在我国的桥梁建设中得到更加广泛的应用。
The unique characteristics of corrugated steel web box girder which are different from those of ordinary concrete box girder mainly manifest in shear connection of corrugated steel webs, external prestressing strands, corrugated steel webs and upper and lower concrete slabs. Aspects. Some units in our country have conducted research on the mechanical properties of corrugated steel web PC composite box girder structure and made important progress. This paper introduces two 2-PC corrugated steel box girder bridges with corrugated steel webs under construction in our country, and discusses the application prospect of this bridge type in our country, hoping to arouse more widespread attention and promote this bridge Type in our country’s bridge construction has been more widely used.
