Abstract
The temporary bridge structure located on the northbound extension of Zhongxin road under-passing Nanjing Yangzi River No. 3 bridge should be of low clearance and large span, possess high anti-vibration capability and may be disassembled quickly. After a comprehensive comparison between Bailey beam and rail D-24 m temporary bridge structures, rail D-24 m structure was finally selected which would best address the above challenges, shorten the construction period and ensure the normal operation of the expressway.关键词
