摘要

合理确定成桥索力是斜拉桥设计的重要一环。根据多年的计算经验总结出刚性支承连续梁法、零位移法、倒拆和正装法、无应力状态控制法、内力平衡法这五种调索方法的具体实现办法,做到设计精准、施工可控,确保桥梁的理论与实际相吻合。采用ANSYS软件实施各种调索理论将给设计者提供更多比选的调索优化方案,这一方法可在设计中应用推广。
        It is an important link to reasonably determine the cable force of finished bridge in the design of cable-stayed bridge. Based on the calculation experience for many years, this paper summarizes the concrete implementation methods of five cable adjustment methods of rigidly supported continuous beam method, zero displacement method, forward erection and backward method, unstressed state control method and internal force balance method. The precise design and controllable construction can ensure that the theory of bridge is consistent with the practice. The software ANSYS is used to implement various theories of cable adjustment and provide the designers with more optimization schemes of cable adjustment for comparison. This method can be used and popularized in the design.
