六律邕江特大桥栈桥码头结构受力分析研究
|
摘要
文章以六律邕江特大桥栈桥码头为工程实例,基于Midas Civil软件建立了栈桥码头模型,分别研究了拱肋、格子梁、龙门吊和动水荷载对模型的影响,并通过对栈桥码头跨中及墩顶处形成的最不利荷载工况的受力分析,证明了栈桥码头的结构刚度、强度及稳定性等均满足要求。
With the trestle wharf of Liulv Yongjiang River Bridge as the engineering example,this article establishes the trestle wharf model based on Midas Civil to study respectively the effects of arch ribs,lattice beams,gantry cranes and dynamic water loads on the model,and proves that the structural rigidity,strength and stability of trestle wharf meet the requirements through the force analysis on the most unfavorable loading conditions formed at the mid-span and the pier top of trestle wharf.
