摘要
以沾临公路黄河特大桥主桥-特大跨径钢-混组合梁斜拉桥步履式顶推为工程案例,通过对步履式顶推施工全过程进行计算分析,研究顶推过程主梁结构及临时支墩受力是否满足受力安全要求。
The walking type jacking of the extra-large span steel-composite girder cable-stayed bridge on Zhanlin high-speed is taken as an engineering case.Through the calculation and analysis of the whole construction process of walking jacking,the main girder structure and temporary support piers in the jacking process are studied whether the force meets the force safety requirements.
