【摘要】 在以往国内外大跨度悬索桥施工中,多采取设置抗风索的措施来提高猫道的抗风稳定性。为加快施工进度和降低费用,对润扬大桥猫道采取调整横向通道的间距和数量的方法来保证其整体抗风稳定性,并增设水平和竖向制振装置减小猫道在活荷载作用下的振动。系统介绍了悬索桥猫道系统的设计与施工。更多还原

【Abstract】 In the previous construction of long-span suspension bridges at home and abroad, the storm strands were often used for catwalks to improve their wind stability. However, in order to accelerate the construction and reduce the cost of the Suspension Bridge of Runyang Bridge, the global wind stability of catwalks of the Bridge is achieved by adjusting the spacing and numbers of cross-bridges connecting the catwalks, and the horizontal and vertical dampers are also added to mitigate the vibration of the catwalks under live loading. In this paper, the design and construction of the catwalk system of the Bridge are systematically described.更多还原
