Research On Construction Technology And Monitoring Technology Of Landscape Cable-stayed Bridge

Since we entered the new century, our economy has developed rapidly.As thedevelopment of our economy,the society infrastructure will be further improved.So itbrings an unprecedented opportunity to the development bridge business.But it is importantfor us that how to use the opportunity properly;The more important thing is how toconstruct brings safety,for avoid accident during the construction process.By virtue ofgraceful bodily form,wide span and else advantage, the cable-stay bridge has beenappreciated.But it is far different between cable-stay bridge and other bridges.During theprocess of construction,it not only relates to construction of main beam,but also theinstalling of the stay cable.Then the construction safety of cable-stay bridge is valuedhighly to the public and bridge designers.Based on Zhongxing Street Bridge on the Middle Rotue of N-S Transfer Channel incity of Xingtai,this article study on measuring method of staved-cable force, especially thesummarizeded calculate method based on vibration measuring.The paper search on bridgeconstructing method and monitoring method. In course of construction of the bridge,thekey points are main beam, bridge tower, chain. In the construction monitoring,we candetermine strategy by open-loop control, feedback control, adaptive control and othermonitoring strategy.By backward method, forward iteration method, stree-free statusmethod, effect matrix method and so on,we can determine reasonable construction state.The Zhongxing Street Bridge create procedure of MIDAS finite element model and theconstruction stage division are introduced in detail in this paper.Then by analysisingconstruction method of main beam, stay cable, practice and experience for constructionsupervision are formulated.While by analysising measurement data during constructionand finite element calculating data,it will insure successful completion of the bridge.
