Research On Construction Monitoring Technology Of Xi Wangzhuang Bridge

With the development of the bridge design and construction technology, the bridgestructure is becoming more and more large and complex.In order to ensure the smoothprogress of the bridge construction. Bridge construction monitoring has been applied tothe bridge construction. Meanwhile the prestressed concrete continuous beam bridgestructure has been widely adopted in bridge construction.This article provides some informations about the structure of prestressed concretecontinuous beam bridge construction features as well as its main processes. In addition,monitoring for the bridge construction were reviewed.The main contents of bridgemonitoring is described in detail and the importance of it were also analyzed in thisresearch.The main object of the article is FeiXian xiwangzhuang bridge constructionmonitoring process, FeiXian xiwangzhuang is a typical span prestressed concretecontinuous beam structure bridge, there are a variety of factors influence it during itsconstruction.The construction of the bridge has become extremely difficult, it isnecessary to monitor the construction of the bridge. The paper uses the Midas/civilfinite element analysis software, Xiwangzhuang bridge is modeled, meanwhile thedisplacement and stress of the bridge were analyzed. Based on the deflection and stressof bridge completion status as control target, to quantitative analysis of the change,identifying the sensitivity of the parameters. Through analyzing we know thattemperature difference has a bigger influence on the control objectives and holedeviation and channel friction coefficient has little effect to control target. Eventuallyproved in this paper, the analysis on construction is important for construction ofFeiXian xiwangzhuang bridge.
