摘要
以某座大跨径多跨刚构-连续组合桥梁为研究对象,运用Midas/Civil进行计算模拟分析,研究分析在不同合龙顺序下对该桥型结构的影响,由计算结果可知,不同的合龙顺序对桥梁线形及桥墩内力有着显著影响,对主梁应力没有实质性的影响,主梁应力的变化取决于结构自身特性。
This paper takes a long-span multi-span rigid frame-continuous composite bridge as the research object,uses Midas/Civil to carry on the calculation simulation analysis,studies and analyses the influence of different closure sequence on the bridge structure.From the calculation results,it can be seen that different closure sequence has a significant impact on the bridge alignment and pier internal force,and there is no substantial effect on the main girder.The change of the stress of the main beam depends on the characteristics of the structure itself.
