Abstract


ABSTRACT:With the development of high-speed railway in China, the steel box composite arch bridge is used as a new structure type in railway construction. Compared with the traditional arches, there are a lot of advantages of this bridge: strong adaptability for long span, advanced construction technology, application of new technology, and high stability of structure. Taken Xinkai River Bridge with the type of steel box composite arch bridge in Haerbin-Dalian high-speed railway line as a project background, manufacture technology and construction processes are discussed in this paper, and the detailed contents are shown as follows:(1) Based on the investigation and analysis of arch bridges, the developments of the domestic and international long-span steel arch bridges and the steel box composite arch bridges are summarized.(2) The manufacture and construction technology of steel box composite arch bridge are briefly introduced.(3) According to the local geography environment and the construction requirement of Haerbin-Dalian high-speed railway line, the method called as "constructing arch after constructing beam" was used to build the steel box composite arch bridge. Many technical problems such as the work of gantry crane at high altitude of 59 meters and the high-accuracy assembling of arch ribs were solved successfully, and it innovatively achieved single phase installation of the arch section with span of 88 meters in China which is significant for spread and application of long span steel box composite arch bridges of high-speed railway in future.(4) The internal forces, stresses and displacements of main forcing members at completion stage and each construction stages are analyzed by using the software of Midas/Civil 2010. The analysis results are compared with the datas obtained by site test. By comparison, the error analysis is taken to make the theoretical datas more closed to the indexs in actual construction conditions and provide a better guide to the construction of the steel box composite arch bridge.
