Main cable anti-sliding device for applying prestress and anti-sliding method of main cable anti-sliding device
The invention discloses a main cable anti-slip device and an anti-slip method thereof, the main cable anti-slip device applying prestress comprises a main cable and a cable saddle used for installing the main cable, cable clamps are arranged on the main cable, an anti-slip inhaul cable is arranged between the cable saddle and the cable clamps located on the two sides of the cable saddle, the anti-slip inhaul cable is a flexible inhaul cable, and the anti-slip inhaul cable is connected with the main cable. The two ends of the flexible inhaul cable are anchored to the cable saddle and the cable clamp in the mode that certain prestress is applied to the two ends of the flexible inhaul cable. When the sliding force of the cable clamp is too large, the main cable anti-sliding device provides upward prestress for the cable clamp connecting structure, and the anti-sliding performance between the main cable and the cable clamp is improved; when a limit unbalanced load exists on one side of the cable saddle of the bridge tower, the main cable anti-sliding device can provide prestress opposite to the sliding direction for the main cable in a self-balancing mode, and the main cable is prevented from relatively sliding in the saddle groove of the cable saddle connecting structure. And meanwhile, the stress characteristics are converted and self-adaptively balanced in the system, and extra loads cannot be caused to other components such as the bridge tower and the stiffening beam.
本发明公开一种主缆抗滑移装置及其抗滑移方法，一种施加预应力的主缆抗滑移装置，包括主缆，以及用于安装主缆的索鞍，主缆上设置有索夹，索鞍与位于索鞍两侧的索夹之间设置有抗滑拉索，抗滑拉索为柔性拉索，使得柔性拉索两端分别以施加一定的预应力的方式锚固在索鞍、索夹上。当索夹下滑力过大时，本发明主缆抗滑移装置给索夹连接结构提供一个向上的预应力，提升主缆与索夹之间的抗滑移性能；当桥塔索鞍一侧存在极限不平衡荷载时，主缆抗滑移装置会自平衡的给主缆提供一个与滑移方向相反的预应力，避免主缆在索鞍连接结构的鞍槽内发生相对滑移；同时其受力特性在系统内部转化和自适应平衡，不会对桥塔和加劲梁等其他构件造成额外荷载。
