Single-side truss type double main cables and suspension bridge
The invention discloses a single-side truss type double main cable and a suspension bridge, and relates to the technical field of suspension bridge structures, the single-side truss type double main cable comprises an upper main cable and a lower main cable, the two ends of the upper main cable and the lower main cable are used for being connected with two anchors on the two sides of a main span respectively, the lower main cable and the upper main cable are located in the same vertical plane, and a height difference exists between the lower main cable and the upper main cable; the two ends of each inhaul cable are connected with the upper main cable and the lower main cable respectively, and the inhaul cables are connected end to end in the direction from one bridge tower to the other bridge tower. According to the scheme, the multiple inhaul cables are arranged between the upper main cable and the lower main cable, the two ends of each inhaul cable are connected with the upper main cable and the lower main cable respectively, and the multiple inhaul cables are connected end to end in the direction from one bridge tower to the other bridge tower. The upper main cable and the lower main cable form the truss type main cable, and the vertical rigidity of the main cable structure is improved. The problems that in the prior art, as the span of the main span of the double main cables which are vertically arranged in a stacked mode is increased, the vertical deformation of the structure becomes large, the vertical rigidity becomes weak, and the stress requirement of the structure is difficult to meet are solved.
本发明公开了一种单侧桁式双主缆及悬索桥，涉及悬索桥结构技术领域，该单侧桁式双主缆包括：上主缆和下主缆，上主缆和下主缆两端均分别用于与主跨两侧的两个锚碇连接，且下主缆与上主缆位于同一竖直平面内，并具有高度差；多根拉索，拉索两端分别与上主缆和下主缆连接，且多根拉索从其中一桥塔向另一桥塔方向首尾相连。本方案在上主缆与下主缆之间设置多根拉索，拉索两端分别与上主缆和下主缆连接，且多根拉索从其中一桥塔向另一桥塔方向首尾相连。使得上主缆与下主缆形成桁式主缆，提高了主缆结构的竖向刚度。解决了现有技术中竖向层叠布置的双主缆随着主跨跨度的增大，存在结构竖向变形变大，竖向刚度变弱，难以满足结构受力要求的问题。
