Analysis On The Advantage Of Bridge Rotation Construction Crossing Over Expressway With Cost Theory

With the development of China’s transportation infrastructure construction, traffic network continues to expand; line bridge construction continues to increase. In order to reduce the influence of bridge construction on the existing railway and highway bridge construction scheme selection is particularly important. The construction scheme including conventional prefabricated steel box Girder Bridge, pushing the construction of continuous beam bridge, cast-in-place continuous beam bridge construction, cantilever construction of continuous beam bridge. These construction projects will have a greater impact on the railway or highway traffic, Swivel construction scheme can minimize the impact on the existing highway or railway. And can effectively save construction materials, reduce construction equipment, the construction of more rapid and safe, will not affect the navigation and the traffic. Swivel construction scheme has strong applicability, can adapt to cross rivers, valleys and other complex terrain. It can make full use of other venues for prefabrication of bridge components, and can effectively save the construction space and shorten the construction period, which can eliminated the long-term impaction on the highway transport.This thesis analyzed the bridge rotation construction Crossing over expressway by taking the north interchange project in Fuzhou as an example with cost theory. We found that the bridge rotation construction technology has greater advantages than other technology. These research results can provide effective theoretical basis and practical reference for the application of rotating construction technique...
