Construction Control Of Yingshanhe Bridge

In this dissertation, from construction aspect the author introduced the purpose, significance and basic theory of construction control of Prestressed Concrete Bridge with rigid frame-continuous composite beam bridge of Yingshanhe Bridge. And Euler to the theory of elasticity , use of space finite element method for thin-walled high pier construction process in the stability analysis made in the construction process should thin high pier construction and "T" Frame Construction of close control by the stability calculation method and results of such bridge stability control provides a reliable basis. Analysis of the different temperature closure of the bridge structure forces, and that closure temperature for Prestressed Concrete Bridge with rigid frame-continuous composite beam bridge the major impact of the pier and piling in the control section of the most unfavorable combination of internal forces , in normal circumstances Closure right choice hypothermia force structure is favorable; The bridge closure with the actual high temperature, Prestressed Concrete Bridge with rigid frame-continuous composite beam bridge closure of the high temperature expected to take anti-imposed maximum of countermeasures, and through structural analysis and engineering practice proved the effectiveness of the measures.
