摘要
结合哈大客运专线56 m预应力钢筋混凝土简支箱梁预应力钢束布置方案比选及预应力钢束布置对梁端应力分布影响的研究,探讨客运专线大跨度预应力混凝土简支箱梁设计时应注意的几个问题,为今后在铁路客运专线工程中推广大吨位张拉钢束在桥梁设计方面的应用提供参考。
In combination with the scheme comparison and study of the steel tendon arrangement and its effects on stress distribution at the end of 56m prestressed concrete beam in Harbin-Dalian passenger-dedicated line,the paper discusses several design problems of simply supported prestressed concrete box beam with long span in passenger-dedicated line,in order to offer some reference for the popularized application of large-tonnage tension tendon of bridge in passenger-dedicated line in future.
