摘要
以山西运宝黄河大桥副桥为研究对象,分别计算以桥跨刚度分布为原则的原设计合龙顺序和考虑施工阶段温度影响为原则的优化后合龙顺序对多跨刚构-连续组合体系波形钢腹板PC箱梁桥的内力影响,并进行了对比分析。提出该体系桥梁合龙顺序要考虑施工阶段温度的影响,可使波形钢腹板组合梁在施工阶段及运营状态下受力更均匀合理,对该类型桥梁在今后的的设计、施工具有一定的指导意义。
Taking the sub-bridge of Shanxi Yunbao Yellow River Bridge as the study object,the effects of original designed closure sequence based on the principle of the bridge span stiffness distribution and the optimized closure sequence considering the influence of temperature in construction stage on internal force of PC box girder bridge with corrugated steel webs in multiple span rigid-continuous composite system were calculated respectively,and the comparative analysis was carried out.In this system,the temperature in construction stage should be considered to determine the closure sequence,which can make the composite beam with corrugated steel webs bear more uniform and reasonable force during construction and operation and has certain guiding significance for the design and construction of this type of bridge in the future.
