Multi-tower cable-stayed bridge adopting combined stiffening cables
The invention discloses a multi-tower cable-stayed bridge adopting a combined stiffening cable, which comprises a main beam and a bridge tower, stay cables are arranged between two sides of the bridge tower and the main beam, the bridge tower comprises a secondary side tower, an inclined stiffening cable is arranged between the secondary side tower and a fulcrum of the main beam, a horizontal stiffening cable is arranged between the secondary side tower and a middle bridge tower, and the main beam and the middle bridge tower are connected through the inclined stiffening cable. The bridge towers comprise side towers located on the two ends, secondary side towers located in the side towers and middle bridge towers located in the secondary side towers. The combined stiffening cable is formed by arranging the horizontal stiffening cable and the inclined stiffening cable, the stiffening effect of the combined stiffening cable is better than that of a conventional mode that only the horizontal stiffening cable is arranged, tower top displacement can be reduced more effectively, and the rigidity of a bridge is improved. No stiffening cable is arranged at the position of the side tower, the characteristics that the side tower is controlled by the side span with large rigidity, the displacement of the tower top is small, and the rigidity of the side main span is large are utilized, arrangement of the stiffening cable is omitted, materials are saved, and meanwhile the landscape effect is improved.
本发明公开了一种采用组合加劲索的多塔斜拉桥，包括主梁和桥塔，所述桥塔两侧与主梁之间设置有斜拉索，所述桥塔包括次边塔，所述次边塔与主梁的支点之间设置有斜向加劲索，所述次边塔与中部桥塔之间设置有水平加劲索，所述桥塔包括位于收尾两侧的边塔、位于边塔内的次边塔、位于次边塔内的中部桥塔。本发明通过设置水平加劲索和斜向加劲索，形成组合加劲索，组合加劲索的加劲效果比常规仅设置水平加劲索好，能更为有效的降低塔顶位移，提升桥梁刚度。本发明在边塔位置不设加劲索，利用了边塔受刚度较大的边跨控制，塔顶位移本身小，边主跨刚度大的特点，节省了加劲索布置，节省材料的同时提升了景观效果。
