The Construction Control Of Bingcaogang Bridge In Panzhihua City

Bridge construction is the key link of building bridge. The level of bridge construction technology directly affects the development of building bridge, and construction control is an important part of construction technology, and runs through all stages in bridge construction.The thesis is the construction control working summary and research result of Bingcaogang bridge in the Panzhihua city, it is detailed the methods, the course, and the effect of this bridge construction control. The structure of the bridge is novel, and the technology is complex, and there isn't nearly same type bridge in our country now.The thesis has summarized the development of the oblique-pull bridge, its construction technology and the importance of bridge construction control, then has introduced project general situation, and has narrated detailed regulation, organization construction, the major work and difficult part of this bridge construction control. The following is the key part of this thesis, firstly, it has introduced the experiment work of early stage, structural calculation and its theoretical result: the absolute altitude of each operating mode, the absolute altitude of building mould in each section and the absolute altitude after pouring concrete; Then, it has discussed the method and content of the line shape control of the main beam, actual absolute altitude of building mould is put forward, and it has described the method of structural stress monitoring, how to arrange measure point and collect data, and how to analyze data. It has also narrated the method of rope force detection and structural temperature inspection. Big bridge suit smoothly approach end establish and transport test as well as safe operation for two year, all of these have proved the reasonability of the inspection and its data analysis handling and correctness of construction control. In the final, it has put forward some suggestion and cognition, and has pointed out existent problem and develop direction.The successful experience of the bridge construction control, has offered in this report, references for the construction control of the same type bridge in the future.
