The Research On Structure Analysis Of Construction Platform Of Deep-water Pier And Construction Technology

With the booming development of bridge construction, bridge construction often face with building bridge pier in the deep-water .It makes present construction technology of construction company of our country face with grim challenge. As a temporary construction structure, construction platform means critical importance to construction operation of deep-water pier in the construction process, construction platform of steel guide-well avail of steel guide-well as brace system in the second Danjiangkou Bridge, it great cross out project cost. This article seem it as of study object and analyze the mechanical character of construction platform of steel guide-well and especial advantage of it compared other construction platform ,and analyze the applying future of construction platform of steel guide-well avail of steel guide-well. At the same time ,the article discuss building methods of temporary construction structure to conduct design ,construction and supervision of temporary construction structure Through the research of construction platform of steel guide-well of the bridge pier in the second Danjiangkou Bridge .The article have a admirable try on methods and principles of the temporary construction structure.At first, this article introduces project profile of construction operation of steel guide-well of the bridge pier in the second Danjiangkou Bridge, and especially present research conditions and prevalent theory at home and abroad of deep-water pile platform and offshore platform that are conformable to it. Through the comparison between them ,the article summarizes some advantages and disadvantages of operation methods for construction operation and mechanics characters.Then, this article see construction platform of steel guide-well of the bridge pier in the second Danjiangkou Bridge as study object ,and apply program Ansys to build mechanical model .At the same time ,through applying the time-frozen theory to model ,the author analyze the mechanical state of the construction platform in the whole process of construction platform.Through analyzing the process of construction , the article find out the controlling state of construction platform in the whole process of construction, and find out key factors that have a great influence on the displacement and deformation of construction platform. Especially, the author avail of birth-death element function of program Ansys to sinulate and analyze the process of construction, and put emphasis on the whole stability of construction platform and steel guide-well that takeconstruction process into account .Then this article analyze the mechanical characters of construction platform when it bear the dynamic load and draw a applied conclusion.At last ,the article summarize the key technology of construction operation of construction platform of steel guide-well. And through analyzing this project example ,the article discuss the general methods and principles construction monitoring of temporary construction structure, and put emphasis on define of informational construction and building of net.
