摘要
Abstract
Unlike single-span suspension bridge,the three-span continuous suspension bridge is mainly characterized by slings set in both side spans,and the continuous transition of stiffening girders between the mid and side spans achieved by girders without slings in the main tower region,and usually restraint equipments set on the side span transition piers to achieve the coordinated deformation between the main cables and stiffening girders in the region,so the lifting method and key construction process for the stiffening girders of the type of suspension bridge is relatively complex. the Fourth Nanjing Yangtze River Bridge as the background,and accord-ing to the structural features of the large span three-span continuous suspension bridge,the reasonable lifting pro-gram is determined through the comparison and analysis on two different types of lifting sequence for steel box girders.关键词
