摘要
将波形钢腹板箱梁作为部分斜拉桥的主梁,有利于降低结构的自重、增大桥梁跨径、减小地震反应;也有利于施工的合理化和工期的缩短,降低施工成本。介绍了日本栗东桥和日见桥这两座目前仅有的、正在施工的波形钢腹板部分斜拉桥的设计、施工与试验研究情况。
The utilization of the corrugated steel web box girder as the main girder of an extradosed bridge advantages the decrease of structure dead weight, increase of bridge span length and mitigation of seismic response, and also helps to rationalize construction, shorten construction time and lower construction cost. In this paper, the design, construction and tests of the Rittoh Bridge and Himi Bridge in Japan, the only two extradosed bridges with corrugated steel webs that are being constructed at present, are dealt with.
