Abstract


With the improved performance of the prestressed concrete materials and related design theory , the application of prestressed concrete structures in civil engineering structure in China is more and more widely , the study Prestressed Concrete Construction in promoting the development of prestressed technology in China , has a very significance. Prestressed concrete continuous rigid frame bridge cantilever construction process , linear beam segment has been poured finished in the latter part of the construction is not adjustable to meet the design requirements in order to ensure the smooth closure of the bridge and the bridge linear , while making the bridge internal force control in the design allow the bridge construction process within the scope of the construction control . In this paper, the northern section of the highway Chongzun the Xishan Ditch Bridge system of continuous rigid frame bridge construction technology . This paper introduces the Xishan Ditch Bridge Project Overview and construction plan for the whole project . According to the characteristics of the bridge , follow the scientific method , combined with the actual design 200 diamond-shaped light hanging basket \200 diamond-shaped light hanging basket construction . Through a comprehensive and detailed analysis and careful implementation of the project to achieve the state-of-the-art technology , economic and reasonable construction easy target , the results obtained can provide useful lessons for the implementation of similar projects .
