| 摘 要： | 基于差值迭代法与无应力状态法原理,提出一种系杆拱桥吊杆张拉控制的计算方法.该方法以设计吊杆成桥内力状态为目标,建立一次成桥计算模型,采用差值迭代法计算合理吊杆张拉力值,以使得成桥状态符合设计要求,以此得出成桥状态吊杆的无应力索长;然后按实际施工步骤建立施工阶段模型.采用无应力状态法.以各吊杆无应力索长来指导吊杆到住张拉...

| Abstract: | Based on difference iterative method and stressless principle,this paper proposed a cacluation method of construction control in tied arc bridge tention.With the objective of internal force conditions of suspenders,a calculation model of bridge was established,and reasonable suspending tension was calculated with difference iterative method so that completed state meets design requirements,and stressless length of suspenders in completed state was obtained,and then based on actual construction steps,a const... |
