等效负载在承力索架设时的应用

Application of Equivalent Load in Installing Catenary

研究目的:对承力索架设引进等效负载概念,使承力索架设速度和安全性有了提高,并对该方法的不足之处作出了分析和解决。研究结果:张力等效的应用不仅可以大大地降低承力索的下锚张力,加快落锚速度,提高施工的安全性,还满足了承力索架设一次到位的要求。

Research purooses： The equivalent load concept is introduced for purposes of enhancing the speed and security of installing catenary. The analyses of its shortcomings are made and the relative measures for them are presented. Research results： Application of equivalent tension not only reduces the tension of catenary, but also enhances its speed and improve construction security. And the requirement of installing catenary in place for one time can be met by this method.
