The High-pier Rigid Frame Bridgessafety Production Management Research

In recent years,with the rapid development of our country highway transportationenterprise,Spanning capacity of bridges is more and more strong,all kinds of long-spanbridge are constructing in our country,which frequently adopted in the construction of prestressedconcrete continuous rigid frame bridge in particular.With the same kind bridge(such ascontinuous girder bridge,T rigid frame bridge):multi span bridge keeps the upper structure of continuous beam properties,has great spanning capacity,less construction difficulty,vehicle body,easy maintenance,low cost advantages.herefore,the number of newly-built bridges in the Chongqing mountainous areas have increased sharply.This thesis has researched and summarized the current situation and tendency of the development of high-pier rigid frame bridges.By using an actual project as an example(the Yujiagou Bridge on the highway from the Zhong County to Wanzhou in Chongqing which was just completed in 2016),this thesis has also researched the safety production management during construction,analyzed the security risk points in every construction procedure and summarized construction safety production management for high-pier rigid frame bridges.The results has shown relatively practical value.The first part explains the significance of the safety management in the construction of the rigid-frame bridge.The second part lists the overall security risk points of high-pier rigid frame bridge,using the Yujiagou Bridge as an example and the construction security risk points in every key procedure.The third part states the essential various safety precautions including the technically specific response to safe production risk points,emergency guarantee.etc and the various things the construction project department should prepare incase of any safety production risks they have to face.Lastly,the forth part puts forward the methods used to encourage the construction control company and construction company to carry out these safety production management work as an owner or supervising company to prevent production accidents with the author’s experience in security examination for Yujiagou Bridge.
