Single spiral arch and truss-cable-stayed combined system bridge
The invention discloses a single spiral arch and truss-cable-stayed combined system bridge, and relates to the technical field of bridges, the bridge comprises a bridge deck system and a supporting assembly, the bridge deck system comprises a main bridge frame and a bridge deck slab, and the bridge deck slab is laid on the main bridge frame. The supporting assembly comprises a spiral supporting arch, a bridge abutment, a bridge tower and a supporting rod, the two ends of the spiral supporting arch are connected with the bridge abutment and the bridge tower respectively, the spiral supporting arch is spirally arranged around the main bridge frame in the extending direction of the main bridge frame and connected to the main bridge frame, the two ends of the supporting rod are connected with the main bridge frame and the spiral supporting arch respectively, and the longitudinal rigidity of the bridge is enhanced advantageously. The spiral supporting arch forms a multi-span space on the bridge deck system, and the space of each span is different in size. The auxiliary piers can be arranged between the bridge abutment and the bridge tower, and the bridge deck system is supported through the inhaul cables, so that the number of the inhaul cables is greatly reduced, a cable net system in the bridge space is simple, and the influence on the driving view is small.
本发明公开了一种单螺旋拱与桁架‑斜拉组合体系桥梁，涉及桥梁技术领域，桥梁包括桥面系和支撑组件，桥面系包括主桥架和桥面板，桥面板铺设于主桥架。支撑组件包括螺旋支撑拱、桥台、桥塔和支撑杆，螺旋支撑拱的两端分别连接桥台和桥塔，螺旋支撑拱沿着主桥架的延伸方向围绕主桥架螺旋设置，并连接于主桥架，支撑杆的两端分别连接主桥架和螺旋支撑拱，有利于增强桥梁的纵向刚度。螺旋支撑拱在桥面系形成多跨空间，每跨的空间大小均不一致。桥台和桥塔之间可设置辅助墩，并通过拉索对桥面系支撑，极大地减少了拉索的数量，使得桥梁空间的索网体系简单，对行车视野影响小。
