Qijiang Concrete Bridge Deck Pavement Disease Analysis Research And Treatment

Recently, the major research of the bridge are focus on the main structure of thebridge, however, the research of bridge deck pavement which used to bear the trafficload is relatively less, especially the less study for bridge paving concrete bridge.At the mean time, the diseases of bridge deck pavement is common and thefrequent of this diseases is increasing, The main purpose of the paper is doing theanalysis on the concrete bridge deck pavement diseases combining with engineeringexampleWith the help of engineering model of Chongqing Qijiang bridge, two kinds offinite element software(MIDAS and ABAQUS) was used to simulate. Through thesimulation of bridge deck pavement defects stress situation, it help to understand thedisease of void in pavement, and measures was put forward at last. By means ofmechanics analysis of paving layer thickness from5cm~10cm in Qijiang bridge, theresult show that the stress of damaged deck pavement decreases with increase ofcushion thickness. This paper also analysis of the influence of overloading on bridgedeck pavement layer stress by mechanics calculation.Through analysis of the bridge deck pavement structure of Pathology, the paperwant to seek improvement methods, with deeply understanding of the pavementdiseases.
