摘要
丫髻沙特大桥是一座三跨连续自锚中承式钢管混凝土拱桥 ,该桥形式新颖、跨度大、结构复杂。依据内力影响面分析的机动法 ,利用大型结构分析软件 SUPER SAP93 ,对该桥主要承重构件的内力影响面进行了分析。
Yajisha Bridge is a three-span continuous half-through,self-anchored,concertefilled steel-tube arch bridge,which is a new type,long span and complex structure.Using the kinematic method for the internal force influence surface analysis,the internal force influence surface of the bridge's main load bearing members are analyzed by the large-scale structrues analysis softwere-SUPER SAP93.The method in this paper can be extended to analyze other complex bridges,and the results can be a reference for the design and anlysis of long-span arch bridges.
