Ground anchor type space cable plane suspension bridge
The invention relates to a ground anchor type space cable plane suspension bridge which comprises two cable bent towers, a main beam connected with the two cable bent towers, two main cables installed on the tops of the two cable bent towers and slings connected with the main beam and the main cables, and the ends of the two main cables extend to the outer sides of the cable bent towers. After the side span approaches to the center of the main beam, the side span downwards penetrates through the bridge floor from the transverse center of the main beam and is anchored on an anchorage; the projection of the main cables on the plane is a variable-distance curve, and the transverse center distance of the two main cables is gradually widened in the direction from the side span to the main beam. According to the ground anchor type space cable plane suspension bridge, on one hand, the downward penetrating positions of the main cables are changed, on the other hand, the transverse distance between the main cables is changed into the variable distance, the main cables do not need to be close to the outer edge of the main beam on the side span side to penetrate downwards, and the main cables do not conflict with the widened main beam or ramp space any more.
本申请涉及一种地锚式空间索面悬索桥，所述悬索桥包括两个索塔、与两个所述索塔连接的主梁、安装于两个所述索塔的塔顶的两根主缆、连接所述主梁与所述主缆的吊索，两个所述主缆的端部均延伸至所述索塔的外侧，在边跨向所述主梁中央靠拢后自所述主梁的横向中心下穿桥面合并锚固在锚碇上；所述主缆在平面上的投影为变间距曲线，自所述边跨至所述主梁的方向，两根所述主缆的横向中心间距逐渐变宽。本发明提供一种地锚式空间索面悬索桥，一方面改变了主缆下穿的位置，另一方面改变主缆间的横向间距为变间距，主缆无需在边跨侧贴近主梁外缘下穿，也不再与加宽主梁或匝道空间冲突。
