某主桥跨中合拢段50m钢梁的整体提升方法及自动控制系统研究

Study on the Overall Lifting Method and Automatic Control System of 50m Steel Beam in the Closed Section of a Main Bridge Span

以汉北河特大桥为工程案例,重点分析了主桥跨中合拢段50m钢梁的整体提升方案,并用midas Civil对钢梁的提升做了模拟分析,通过对桥跨中合拢段50m钢梁的整体提升方案及自动控制系统的研究,以推广其合理利用。

The Hanbeihe Super Bridge is an engineering case,focusing on the overall lifting scheme of the 50m steel beam in the closed section of the main bridge span,and midas Civil simulation analysis of the lifting of the steel beam.Through the study of the overall lifting scheme and automatic control system of the 50m steel beam in the closed section of the bridge span are studied,in order to promote its reasonable use.
