Control Technique For Construction Of Continuous Bridge With High Side Pier

Abstract:As the construction method of continuous bridge with high side pier is peculiar, the requirements on the control technique for construction are more strict. This paper taking Tangxi continuous bridge of Shanghai-Kunming Passenger Dedicated Line as the research background. Combined with the construction process of this bridge, this paper based on theoretical calculation results,use of artificial neural networks and other measures to study the control technique for continuous bridge with high side pier. Achievements are as follows:1、In this paper, control theories and methods of bridge construction has been summarized,and the work of comparing been conducted for these theories and methods.2、Studying on different bridge linear rides and different internal force states with different construction methods.Optimization of construction scheme for this bridge has also been done.3、With the design information of Tangxi continuous bridge of Shanghai-Kunming Passenger Dedicated Line, using the finite element software to conduct simulation calculating and analysis researching of the whole construction process of this bridge,and the result was used in the control for construction of this bridge.4、Using of artificial neural networks to conduct control for construction of Tangxi continuous bridge of Shanghai-Kunming Passenger Dedicated Line, the results show that the method can meet the engineering accuracy requirements on the control for construction of the bridge.
