摘要
为指导临猗黄河大桥初步设计,确定初步设计推荐方案,利用桥梁全寿命周期分析方法,对重点推荐的钢箱组合梁与混凝土连续刚构两个初步设计方案进行分析,从桥梁建设到运营结束全寿命期内的成本进行分析比较。结果表明:材质为耐候钢的钢箱组合梁桥型全寿命周期成本最低,确定该方案为初步设计推荐方案。
In order to guide the preliminary design of Linyi Yellow River Bridge and determine the preliminary design proposal,by using the life cycle cost analysis of the bridge,the two highly recommended design schemes of steel box composite beam and concrete continuous rigid frame were analyzed and compared in terms of the life cycle cost from the beginning of the construction to the end of the operation.The results showed that the steel box composite beam bridge made of the weathering resistant steel had the lowest life cycle cost,which can be the most recommended for the preliminary design.
