摘要
用波形钢板取代传统PC箱梁的腹板,能够大大减轻PC箱梁的自重,改善梁体的受力状况,节省材料,同时可以减少下部结构的工程量,从而降低工程造价。介绍了波形钢腹板预应力混凝土箱梁的结构和几座桥梁的施工方法。
Using waveform steel web to replace conventional PC box girder web may greatly reduce dead weight of PC box girder, meliorate strain condition of girder body and save material, also it may reduce project volume of lower structure and reduce project cost. This paper introduces structure of waveform steel web prestress concrete box girder and construction method for several bridges.
