This paper also presents the methods of controlling unstressed length of cable , pre - displacement of saddle , anchor span tension , erection of wire strands , the fixed position for erecting cable band and cable length . determination and control approach of displacement of saddles during cable erection are also introduced . at the same time , the change course of linetype during construction period for suspension bridge is analyzed 再次，介绍了悬索桥的施工控制内容与方法，利用软件sgkz2000对多座悬索桥进行了施工计算，提出本文关于悬索桥的主缆无应力长度控制、索鞍预偏量控制、锚跨张力控制、丝股架设控制、索夹安装位置与吊索长度控制的方法；介绍了吊梁阶段鞍座顶推量的确定与控制方法，分析了施工阶段悬索桥的线形变化过程。
The main factors which affected the flight stability quality included : forward flight speed , slung - load and helicopter mass ration , slung - load aerodynamic forces and cable length , etc . through adjusting the above structure and performance parameters , rational flight parameters can be decided , which can ensure the safe helicopter mission operations of the slung - load flight 影响飞行品质稳定性要求的主要因素为:直升机飞行速度、吊挂物/直升机质量比、吊挂物气动特性、吊挂钢索长度等。通过对上述结构参数、性能参数的调节,可确定合理、经济的飞行参数,保证安全、高效的完成直升机机外吊挂飞行运输任务。
