Buckle Cable Force Optimization Study Of Arch Bridge In The Buckle Hang Construction

Arch is the oldest one of the basic bridge, with a magnificent appearance, spanning capacity, carrying capacity advantages. The past 10 years, with the construction of long span arch bridge in China has accumulated rich experience in the design and construction. Both static and dynamic characteristics of the theoretical research, or in the design and construction, it is the rise of new CFST arch bridge and large span steel box arch bridge research has a very mature and improve. Since the method of cables tether hoisting buckle hang construction has been used in Yong ning yongjiang bridge , the researchers has launched the key technology research of MTR buckle hang stage, especially carried out a lot of research work on cable force calculation problems and the linear control problem during the buckle hang stage. Although the many research which have guided the bridge construction, However, with the strand in the cable-stayed cable-stayed as the use of buckle cable, which calls for the cable stayed buckle cable force calculation is more accurate. In view of this we pass on the detailed description of the construction process, and on this basis, the important theory of the process were studied in order to put forward a more accurate calculation of cable-stayed cable force.This article aims to explore how to better achieve the stayed suspension and simulation phase, thereby enhancing the cable stayed buckle cable force calculation accuracy. First papers made a system introduction on the construction of cable-stayed suspension using in the arch, followed the construction of cable-stayed suspension system components and construction process is summarized, and then Analying and summarizing some of the main theory of researching MTR buckle hang .Iterative geometric method for linear transformation is proposed through the forward algorithm and the iterative algorithm study, based on the actual works in the buckle cable stayed suspension and cable force were optimized. Analyzing that deviation of the tower should be controled strictly, the numerical analysis that tower deviation should be strict control, nonlinear temperature greater impact on the linear and difficult to control. Research successfully applied Kuige bridge, good results obtained.Linear transformation based on the geometric iterative method was Proposed in this paper, achieving a cable-stayed suspension and process simulation, which is in the cable-stayed suspension and arch analysis of the process provides a good solution.
