摘要
结合不同跨径预应力混凝土简支板梁工程实例,按新旧桥涵设计规范进行了拓宽前后活载内力计算,归纳了活载内力在这些情况的变化及趋势,以积累桥梁设计经验,提高桥梁设计水平。
Based on the different span pre-stressed concrete simply-supported plate girder bridge,the paper calculate the live load internal force according to new and old bridge design standard.The changing trend of live load internal force is summarized,so as to accumulate bridge design experience and improve bridge design level.
