自锚式悬索桥吊索张拉有限元模拟方法研究

Research on Finite Element Method Simulation in Suspender Tension of Self-anchored Suspension Bridges

基于自锚式悬索桥施工过程中吊索张拉对成桥线形和内力的影响,借助ANSYS有限元程序对吊索张拉采用不同方法引起的结构内力进行了分析和比较,得出了适合施工的吊索张拉方法。

Based on the influnence of the tensioning process of the suspension rod on bridge shape and internal forces.in self-anchored suspension bridges construction with the help of ANSYS, the dissertation builds the theory model taking into consideration the tensioningprocess of the suspension rod on bridge shape and internal forces using different ways, draws conclusion of the tensioning process of the suspension rod for construction.
