Research About Linear Control Of Long-span PC Continuous Rigid Frame Bridge In Construction Completed

Cantilever construction method is one of the main construction methods for modernlong-span PC continuous rigid frame bridge. In order to ensure that the linear attain the designdemands, we must monitor linear in the construction process. And an efficient theory ofmonitoring and computational methods is the key which need to solve recently.In this paper we choose the linear control in modern long-span PC continuous rigidframe bridge construction phase as the subject and choose Nu River Bridge in Yun Nan LiuBing highway as the prototype, sum up the theory of monitoring on the construction oflong-span PC continuous rigid frame bridge, and then we build the computational model byMIDAS/Civil,which is a special civil engineering design software for structural analysis andoptimization. We research impact law and the calculate method by many factors, such asweight, pre-tension, concrete shrinkage and creep, hanging wet weight of concrete and othertemporary loads, after crop permanent load,etc. This provides a reasonable basis for theelevation in every construction phase in reality.The research of this article is of high of the long-span PC continuous rigid frame the NuRiver Bridge in Yun Nan Liu Bing highway reference value to guide the design andconstruction bridge, and it has been used in the construction of Highway.
