| 摘 要： | 讨论了拱肋吊装过程中扣索调整的计算问题,综合迭代模拟计算和扣索垂度修正等方法来模拟吊装计算中的扣索调整.实现了拱肋吊装预测计算中对扣索张拉操作的模拟,并给出了扣索调整计算的基本框架.通过工程实例验证了该方法可用于钢管混凝土拱桥拱肋吊装过程中,计算任意一个节段的扣索调整,最终可使拱肋线型满足设计精度要求.

| Abstract: | A method of simulating the operation of cable adjustment in the rib-assembling computation is proposed by means of the iterative approaches and amending the cable gravity effect. The predictive computation is provided in arch rib hoisting,and the common steps of the cable adjustment computation are given.Finally a computation example of construction is carried out to prove the feasibility of the method.The calculation results show that the principles can be applied to the cable adjustment calculation of each section during the suspension construction of arch ribs. |
