系杆拱桥装配施工和吊杆索力调整探索

Exploration on tie bar arch bridge assembling construction and boom rope force regulation

结合工程实例,介绍了下承式钢筋混凝土系杆拱桥在支架上装配的施工技术,分析了吊杆间索力不均衡的原因,探索了吊杆索力调整的计算方法,通过索力调整,以使系杆变形趋于均匀,总索力保持不变。

Combining with engineering example, it introduces constructing technique of next receiving type steel bar concrete tie bar arch bridge in support installation, analyzes unbalanced reasons of rope force among booms, explores calculating measures of boom rope force regulation, according to regulate rope force, in order to make tie bar distortion tend to equality and gross rope force keep constant.
