摘要

建立了均匀流作用下考虑主缆三维效应、主缆间气动干扰效应和双向流固耦合效应的四主缆悬索桥单侧并置双主缆振动分析方法。针对主跨2180m单跨吊四主缆悬索桥方案，开展了均匀流作用下成桥状态中跨主缆横向振动、边跨主缆的横向和竖向振动分析，结果表明：对于中跨主缆，主缆平均位移随风速增大而增大，主缆在平均位移附近做简谐振动，振动的频率与风速相关，双主缆间中心间距随来流风速增加而逐渐减小，但双主缆间不会接触；对于边跨主缆，特定风攻角下，背风侧主缆存在尾流驰振现象。

Abstract

A vibration analysis method for single-side juxtaposition dual main cables of four-main-cable suspension bridges considering the three-dimensional effect of the main cables, the aerodynamic interference effect between the main cables and the two-way fluid-structure coupling effect under the action of uniform flow is established. For the single-span suspension bridge with four main cables with a main span of 2180m, the lateral vibration of the mid-span main cables and the lateral and vertical vibration of the side-span main cables under the action of uniform flow are carried out. The results show that: for the mid-span main cables, the average displacement of the main cable increases with the increase of wind speed. The main cable performs simple harmonic vibration near the average displacement. The frequency of vibration is related to the wind speed. There is no contact between the cables; for the side span main cables, the main cable on the leeward side has the phenomenon of wake galloping. Under specific wind angle of attack, the main cable on the windward side may also have galloping vibration.
