| 摘 要： | 对于塔梁固接体系的斜拉桥,塔梁之间的刚度比将直接影响塔梁的荷载分配比例,而对于桥塔倾斜的无背索斜拉桥,塔梁刚度比的确定将更为困难和重要.通过总结长春市伊通河斜拉桥施工仿真计算采取的方法,提出一些通过调整杆系模型抗弯刚度来模拟真实桥塔刚度的看法,希望可以为类似工程提供借鉴.

| Abstract: | For cable-stayed bridge with fixed pylon and beam,the stiffness ratio between pylon and beam will directly affect the distribution ratio of load,whereas,if the pylon is tilted and without back-stays,the determination of the stiffness ratio will be more difficult and important.In this paper,the author sums up the approaches used in the construction simulation of Yitong River cable-stayed bridge,proposing a view: of simulating the real stiffness of the system by adjusting the bending stiffness of truss model,... |
