摘要
下承式钢管混凝土拱桥是码头大跨栈桥的主要形式之一,由于码头建设的特殊性,其荷载形式及动力特性同一般公路和市政桥梁有很大区别。基于恒力石化(大连)炼化有限公司30万t级原油泊位栈桥工程,利用空间杆系有限元模型,采用弯曲能量最小法对大跨下承式钢管混凝土系杆拱桥的合理成桥索力进行了计算与优化,并针对栈桥的不同受荷状态对其动力特性进行了分析。
The through concrete filled steel tube arch bridge is one of the main long-span trestle bridges in wharf. Owing to the particularity of wharf construction, its load form and dynamic property are different from the general highway and municipal bridges. Based on the 300 000 t-class crude oil berth trestle bridge project of Hengli Petrifaction(Dalian) Refinery Limited Company, the spatial member system finite element model is used to calculate and optimize the reasonable cable force of long-span through concrete filled steel tube bowstring arch bridge by the minimum bending energy method, and to analyze the dynamic properties of the trestle bridge at the different loading states.
