近年来,我国交通水运事业蓬勃发展,对大量内河航道进行了升级、改造。航道等级的提高对原有桥梁的改造利用也提出了较高要求。本文通过对苏申内港线航道改造工程中江浦路吴淞江大桥的顶升设计方案研究阐述顶升移位技术在航道桥梁改造中的应用。 In recent years, China’s traffic and water transport industry has been booming, upgrading and transforming a large number of inland waterways. The improvement of waterway grade also put forward higher requirements on the reconstruction and utilization of the original bridge. In this paper, the design of jacking up of Wusong River Bridge in Jiangpu Road in Sushenne Port Line Waterway Reconstruction Project is introduced to illustrate the application of jacking displacement technology in waterway bridge reconstruction.
