摘　　要：大连福佳大化大型芳烃联合装置码头工程为8万吨栈桥式码头,其栈桥由两跨空腹桁架拱式钢桥组成,在竖向荷载作用下这种结构受力兼有拱结构和桁架结构的受力特性。采用大型有限元软件建立了空间梁单元模型对该种结构的受力性能进行了分析,研究结果表明该桥型结构受力合理,用料节省,能够满足工程需要,可为同类结构设计参考。The wharf engineering with large - scale aromatics complex plant of Dalian Fujia Dahua Petrochemical Co. , Ltd. is an eighty - thousand - ton trestle bend wharf, which is composed by double - span arched vierendeel truss steel bridge. Under the effect of vertical load, this kind of structure stress has the mechanical characteristic of arch structure and truss structure. The spatial beam element model is established by adopting large - scale finite element software, and the mechanical behavior of this kind of structure is analyzed. The research result shows that this kind of bridge is with reasonable stress and saved materials, which can meet the engineering requirement and provide reference for similar structure design.
