摘要
Abstract
Nongye road expressway project crosses over the north marshalling yard of more than 30 tracks and Beijing-Guangzhou railway in Zhengzhou, and the existing road under the bridge passes through under the Zhengzhou north marshalling yard. There are many frame bridges and road bridges at the work site and the number of feasible pier location for the bridge is very few, which challenges the construction of the bridge. Thus, it is absolutely necessary to study and choose a reasonable bridge type for the project. The researches on some feasible pier locations and the selection of feasible construction program and span arrangement result in the determination of 4 bridge types, and one reasonable bridge type is recommended after analysis and comparison in terms of railway safety, technology, schedule and economy. The results show that the ( 126+200+126 ) m twin tower cable-stayed bridge is the recommended bridge type. The research process and method employed may provide references for the design of similar projects.关键词
