Study On Method And Systems Of Construction Post-evaluation Of The Simply Supported Continuous Beam Bridge In Chongqing Expressway

In the rapid development of China’s bridge construction today, by summarizing theexisting bridge construction and research (post-assessment of the bridges) to facilitatefollow-up bridge building is almost empty, but the bridge construction, especially someof the new bridge construction in some of the problems due to lack of preliminarystudies and experiments, resulting in the presence of the bridge " Deficiencies"phenomenon, some common problems are still not resolved, the project quality defectsrepeated; the other hand, due to the heavy construction tasks, leds to the concept ofimportance to the construction, conservation contempt，failed to recognize up bridgescustody from the source of bridge design, construction quality, leading to some"problems" in the custody of the bridge is always present and generally appear. Thus, agreat need to look back on the bridge construction, ie: carry out the constructionpost-evaluation of the bridges, in order to sum up experience, improve bridge design,construction and maintenance techniques and technology, and constantly improve thequality and level and bridge construction and conservation.This paper investigated the design, construction, custody situation of simplysupported continuous beam bridges in Chongqing Expressway. Research to view thedesign, construction, custody documents, supplemented by typical road construction,bridge typical survey research and disease analysis to identify the "construction (design,construction, custody)" and "the existence of a bridge problem" of relations between.Diseases of Shizhong highway bridges be investigated and evaluated for its design,construction and custody aspects.For Chongqing Expressway simply supported continuous beam bridge of large,fast construction, set up a comprehensive methods and systems of constructionpost-ecaluation that can be used to reflect the design, construction, constody. Themethod and system used in Shizhong highway simply supported continuous beambridge construction post-evaluation, and further use the construction post-evaluationmethod and system to evaluate part of bridge in Chongqing Expressway. Summarizesthe problems existing in the highway simply supported continuous beam bridge, and thefuture of bridge design, construction and operation of custody put forward Suggestionsand countermeasures, for future bridge construction and scientific custody further perfect provide first-hand data and experience for reference, has important practicalsignificance.
