Construction Controlling And Optimization Analysis Of Large-span Cable-stayed Bridges

As construction technology continues to improve and the rapid development of finiteelement technology, large-span cable-stayed bridges not only to achieve the theory ofrationality, and in engineering, but also to the security and reliability. Large-spancable-stayed bridges in construction control while it is still in the development stage,however, the cable-stayed bridges construction process, the role has becomeincreasingly significant.This document focuses on the Cairo Bridge in Linyi city as an example of theconstruction control optimization analysis, its main research work are as follows:（1）It briefly describes that the cable-stayed bridges in the domestic and internationalconditions in the development of the space;（2）It briefly describes the bridge construction control theory, methods and its roles,from a macro perspective describe the bridge construction control;（3）It is a project-based, and use of FEM program Midas Civil, the actual works forsimulation analysis, and the results with the engineering field-measured data forcomparison and analysis, to determine if the construction quality, for the construction ofthe control issues can be identified in a timely manner and to amend;（4）In order to ensure construction control itself to achieve the desired effect, it takesfinite element analysis, impact analysis process need to find reasons of constructioncontrol data changes, and analysis and simulation to achieve adjusted for the accuracyof the results;Finally, for cable-stayed bridges construction control, it gives a brief summary,construction control over the process of the problems faces by the need to improve therecommendations, and the outlook for construction control of the future development.
