摘要
结合九畹溪大桥实例 ,介绍在特殊地形条件下 ,大跨度钢管混凝土拱桥 1m钢管拱管内混凝土两岸对称、上下游不对称的泵注方法 ,在该桥施工中首次采用扣索参与承担荷载代替施工配载 ,节约了工程成本 。
A concrete pumping method of symmetric casting at two banks and non\|symmetric casting at upstream/downstream was adopted for pouring concrete into the 1 m steel tube of a long span concrete steel tube arch bridge—Jiuwanxi Bridge under special landform conditions. Fastening cable was applied for the first time in China to bear load replacing loading in construction, which saved project costs and speeded up the construction.
