大跨度钢管混凝土拱桥吊装过程扣索受力分析
Mechanical Analysis of Supporting Cable of Long-span Concrete-filled Steel Tube Arch Bridge in the Process of Lifting
【摘要】 拱肋吊装是湘西王村钢管混凝土拱桥施工的一个关键工序,其中扣索内力的计算对施工控制具有重要的意义。分别采用力法和有限元分析法进行扣索内力计算,经过对比分析,得出了相关结论,可供类似工程借鉴参考。
【Abstract】 The lifting of arch rib is a very important working procedure. The mechanical analysis of supporting cable is a significant procedure for the construction control. In this paper, the authors calculated the force of supporting cable in the process of lifting arch rib using two methods. The important results are obtained through comparative analysis.
