Research Of Construction And Finite Element Analysis About Concrete Filled Steel Tubular Arch Bridge

The arch bridge is one kind of very applicable bridges, and it is very important to go deep into the research of the construction control engineering. The bridge construct and control is the hinge to ensure macroscopic quality of bridge construction. Macroscopic quality standard of construction weighing bridge is whether the bridge state linear as well as receives energetically the circumstances to fit the design requirement. The bridge construction control also is the safe guaranty of bridge construction.This thesis was chiefly introduced the content of following several aspects: â‘  two kinds of construction methods of big span concrete filled steel tubular arch bridge: The thick rope hoists law and the turn construction law. It expounds the developing condition, construction characteristic and the constructing controlled major content of these two methods. Among them stressly introducing the nothing support thick rope hoists the oblique knot pulling of hoisting jack and hangs the construction procedure as well as the most advantageous and shortcoming of law.â‘¡ The structure calculation method in constructing to control is loading the analysis law and inverts analyses the law and does not have the stress status analysis law.â‘¢It introduces the Error analysis, parameter identification and calculate with the state in constructing control. It detailed expounds design parameter which causes the structure state deviation, sensitivity analysis of design parameter and state forecasting method - least square method, including the basic principle and the least square method application in the bridge parameter estimation.The constructing control of steel tube skeleton hoists is a systems engineering, and involves the content of many aspects, including defining of construction scheme, the humps up rib steel tube joint section divides, fully preparation of all work before hoisting, Supervision monitoring in the construction course etc. Every link is all very important. This thesis combines a big bridge of acrossing ocean named San-Menkou which lies in Xiangshan of Ningbo in Zhejiang province as a living example analyzing.
