The Analysis Of Calculation Theories And Principle Of Construction Control For Concrete-Filled Steel Tube Arch Bridge

With the increase of the span of the concrete-filled steel tube arch bridge, the development of bridge structure analysis,design theory and construction technology are promoted.It is not difficult to find that currently certain urgent problems still exist in the development of concrete-filled steel tube arch bridge,when the history and experience of is reviewed and summarized.Faultiness appeared during the study of the stability,ultimate bearing capacity and dynamic properties,and stability problem stands out specially; The monitoring measures of the construction process is relatively backward.The exist of mentioned problems will be a key constraint to the development of the arch bridge for a quite long time period in the future the joint efforts and the Cooperation.Of bridge scholars are needed necessarily.Take the Post-disaster reconstruction of Yang mao ping bridge as the backing projecfor for the search and study the calculation theory of concrete-filled steel tube arch bridge and find out the reasonable calculated method.Using professional finite element software, to analyze the ultimate bearing capacity and stability of this project.Combining the reconstruction of Yang mao ping bridge and the method of bridge construction control, study more reasonable and practical control method, establish sophisticated bridge construction control technology and organizational management system and improve the bridge construction technology and organization and management system for the theory of calculation and Construction control of concrete-filled steel tube arch bridge in reference to the further development of our country.
