以某中承式系杆拱桥为工程背景,就变截面钢管混凝土拱桥的主拱肋节点,确定作了初步探讨分析,实践证明利用研究的方法和程序较易确定节点坐标,为相关工作的开展积累了经验。%Taking some half-through tie bar arch bridge as the engineering background,the paper identifies the primary exploration and analysis of the main arch rib＇s node of the variable cross-section steel-pipe concrete arch bridge,and proves by the practice that the methods and the procedure of the research are easier to identify the node coordinate,so as to accumulate the experience for the relative work.
