Novel auxiliary cable-stayed bridge and shape finding method thereof
The invention relates to the technical field of cable-stayed bridges, in particular to a novel auxiliary cable-stayed bridge and a shape finding method thereof, and the novel auxiliary cable-stayed bridge comprises a main tower, an auxiliary tower, a main beam, a stay cable, a main cable, an auxiliary cable and the like. And the auxiliary tower is arranged at the auxiliary pier or the side pier. The main cable crosses the auxiliary tower and the saddle at the top end of the main tower, and two ends are anchored on the anchor structures. The main cable is higher than the cable face of the stay cable, and auxiliary elastic support is provided for the stay cable. The two ends of the stay cable are connected to the main tower and the main beam respectively. One end of the auxiliary cable is connected with the main cable through a cable clamp, and the other end is serially connected with a plurality of long inhaul cables. The corresponding shape finding method comprises a stay cable shape finding method and a main cable shape finding method. By means of the method that the auxiliary cables are connected with the stay cables in series, the horizontal projection length and the self-weight sag of a single cable unit can be reduced, the equivalent elastic modulus of the long stay cables is improved, and larger supporting rigidity is provided for a main beam; the shape finding method is very convenient, and line shapes of the stay cable and the main cable are convenient to determine.
本发明涉及斜拉桥技术领域，涉及一种新型辅助索斜拉桥及其找形方法，新型辅助索斜拉桥组成部分包括主塔、副塔、主梁、斜拉索、主缆、辅助索等。副塔设置于辅助墩或边墩位置。主缆跨过副塔、主塔顶端的鞍座，两端锚固在锚锭结构上。主缆高度高于斜拉索索面高度，给斜拉索提供辅助弹性支撑。斜拉索两端分别连接在主塔和主梁上。辅助索的一端通过索夹与主缆相连，另一端串联起多根长拉索。相应的找形方法包括斜拉索的找形方法和主缆找形方法。本发明利用辅助索串联斜拉索的方法，能减少单根索单元水平投影长度和自重垂度、提高长拉索的等效弹性模量，给主梁提供更大的支撑刚度；找形方法十分方便，便于确定斜拉索和主缆的线形。
