Arc-shaped cable strand anchoring system for anchorage of suspension bridge
The invention discloses an anchoring system for an anchorage arc-shaped cable strand of a suspension bridge. The anchoring system is provided with a straight line section L1, an arc section L2 and a straight line section L3; wherein the straight line section L1 is located near the corresponding front anchor surface and is in a divergent shape, the front end of the straight line section L1 extends and then intersects at a splay cable saddle IP point, the straight line section L3 is a parallel straight line section and is parallel to the center line of a main cable, the arc section L2 is connected with the straight line section L1 and the straight line section L3, and the divergent posture of the front end is changed into the parallel posture of the rear end. The invention has the following advantages: (1) the size of the anchorage is reduced, the cost is saved, and the construction period is shortened; (2) the excavation volume of the anchorage is reduced, and the safety in the excavation process of the anchorage is improved; and (3) the concrete volume of the anchorage is reduced, so that the mass concrete construction quality is favorably controlled.
本发明公开了一种悬索桥锚碇弧形索股锚固系统，其特征在于；该锚固系统具有直线段L1、圆弧段L2、直线段L3；其中，直线段L1位于对应的前锚面附近，呈发散状，前端延长后交于散索鞍IP点，直线段L3为平行直线段，与主缆中心线平行，圆弧段L2连接直线段L1和直线段L3，将前端的发散姿态变成后端平行姿态。本发明具有如下优点：（1）减小锚碇体积，节约造价，缩短施工周期；（2）减小了锚碇的开挖量，提高了锚碇开挖过程中的安全性；（3）锚碇混凝土体积减少，有利于控制大体积混凝土施工质量。
