摘　　要：钢管桁架拱组合式系杆拱桥是指采用钢管混凝土拱肋,跨中局部范围布置单榀拱肋、其余两侧采用双榀成提篮式,或在满足建筑限界要求范围内设平行式的拱桥,其二榀间一般采用框架式联结系。为了贯彻上述制定单榀拱肋组合式系杆拱方案的要点,特选定某三跨连续系梁下承式钢管桁架拱肋系杆拱为例,说明拱桥的设计思路及稳定性分析方法。The combined tied arch bridge of steel tube truss arch refers to an arch bridge with concrete-filled steel tube arch ribs,single arch ribs arranged locally in the middle of the span,and double arch ribs formed into baskets on the other two sides,or a parallel arch bridge set within the scope of meeting the requirements of building clearance.Generally,the frame type connection system is used between the two frames.In order to implement the above key points of formulating the scheme of single arch rib combined tied bar arch,a three span continuous tied beam through steel pipe truss arch rib tied bar arch is selected as an example to illustrate the design ideas and stability analysis methods of the arch bridge.
