【摘要】 本文简要介绍了重庆市长江大桥的建设情况,并以重庆菜园坝长江大桥为例,介绍大跨度拱桥的抗风性能的相关研究工作。从主拱节段模型静力三分力试验,节段三分力计算流体力学模拟.两榀拱肋的干扰效应,全桥成桥状态和施工状态全桥气动弹性模型的设计和风洞试验,拱桥的涡激共振,拱桥三维随机风场的模拟等方面说明研究的方法和结果。更多还原

【Abstract】 An overall development about bridges construction in Chongqing is introduced in this paper, and research on aerodynamic of long-span arch bridge is reviewed with the example of the Chongqing Caiyuanba Changjiang bridge. The results and research methods of wind resistant performance of long-span half through arch bridge are proposed .The content includes the wind tunnel test of measuring static wind forces on the arch model, and the numerical simulation of the static wind forces by the computational fluid dynamics, and interference effects on the two arches, and design and tunnel test of the aeroelastic models of construction and complete stage , and vortex-induced vibration of Arch bridge, and numerical simulation of three-dimensional wind field.更多还原
