基于前进迭代法的钢管混凝土拱桥施工控制

Construction control of concrete-filled steel tube arch bridge based on forward iteration method

结合钢管混凝土拱桥的发展,在研究传统倒退分析与前进分析的优缺点后,针对广泛使用的无支架缆索吊装方法,提出了前进迭代法来解决大跨钢管混凝土拱桥的施工控制分析,通过工程实例,验证了本方法良好的精度和易行性。

Combined with the development of concrete-filled steel tube arch bridge. After studying the advantages and disadvantages of traditional regression analysis method and forward analysis method, in view of widespread use non-support cable hoisting method, a kind of forward iteration method is proosed to resolve the construction control analysis of the long-span concrete filled steel tube arch bridge. Through the project example, this method is proved precise and convenient.
