Study Of Detection, Evaluation And Reinforce Technology About Construct Of Bridge

With the reconstruction of old road , the upgrade of road scale , the accretion of traffic quantity and the manifold of heavy vehicle in my country recently, Our desire is higher and higher about the transit capacity of the old bridges. It is more impendent to confirm practice status and supporting load of these bridges on the calzada. Therefore, detection , evaluation and reinforce of bridges have become one important guarantee that ensures safety maintenance and normal use of it. So, how to perform quality detection .evaluation and reinforce of bridges has become a research hotshot of foreign academia and domain of engineering.This paper deploys research about the damnification identify, employ capacity and reinforce technology with reason of Double bend arch bridge through finding out disease position of construct and cause, colligating these result of the actual bridge detection and load test and analysis and research on the theoretics of damnification ,and so on,despending on a lots of measure and means ,finding out its present condition and checking structure internal force through choosing the proper mechanics model according as a lots of prototype information.To evaluate a bridge, we need not only identify structure parameters by real-time monitoring , analyzing and evaluating actual macroscopical behaviors, but also we need forecast and evaluation structure by means of diversifications of structure parameters relative to environments condition and diversifications of structure parameters during produce and development of structure component's crack, damage, corrosion.
