摘要
兰州雁盐黄河大桥为下承式三跨连续钢管混凝土刚架系杆拱桥,本文就横梁吊装施工方案调整后在施工阶段和成桥状态进行了静力计算与稳定评估,验证了调整后施工方案的可行性并取得了很好的经济和社会效益。
Yanyan Yellow River Bridge in Lan Zhou is a concrete-filled steel tubular through tied-arch bridge.This paper intcoduced the static calculation and stability analysis on the construction and concluded that the adjusted lifting sequence of the crossbeam are feasible approach and have better economic benefit.
