Ground anchor type suspension bridge structure suitable for special terrains
The invention relates to a ground anchor type suspension bridge structure suitable for special terrains. One end of the ground anchor type suspension bridge structure is fixed to a flat-terrain bank, the other end of the ground anchor type suspension bridge structure is fixed to a steep-terrain bank, and the ground anchor type suspension bridge structure comprises a first stress system, a second stress system and a third stress system; the first stress system is composed of a main cable, a cable bent tower, a novel rolling shaft type cable saddle, a main cable saddle, a splay cable saddle, a tunnel type anchorage and a gravity type anchorage; the second stress system is composed of a steel truss stiffening beam and a sling; and the third stress system is composed of a ground anchor structure, a vertical ground anchor sling, a central buckle stay cable and a cable clamp, the first stress system and the second stress system participate in overall stress of the structure, and the third stress system bears live loads and transmits the loads to a steel truss stiffening beam. The ground anchor type suspension bridge structure suitable for the special terrains is a suspension bridge type which is novel in structural form, high in spanning capacity, small in excavation volume and blasting volume, short in construction period, considerable in economic benefit and environmentally friendly.
本发明是一种适用于特殊地形的地锚式悬索桥结构，一端固定于地势较平坦岸，另一端固定于地势陡峭岸，包括第一受力体系、第二受力体系和第三受力体系；第一受力体系由主缆、索塔、新型滚轴式索鞍、主索鞍、散索鞍、隧道式锚碇和重力式锚碇构成；第二受力体系由钢桁加劲梁和吊索构成；第三受力体系由地锚结构、竖向地锚吊索、中央扣斜拉索以及索夹构成，第一受力体系和第二受力体系参与结构的整体受力，第三受力体系承受活载，并将荷载传递到钢桁加劲梁上。该适用于特殊地形的地锚式悬索桥结构是一种结构形式新颖、跨越能力强、开挖量和爆破量少、施工工期短、经济效益可观、环境友好的悬索桥桥型。
