Seagull-type space dorsal cable-stayed bridge system
The invention relates to a seagull-type space dorsal cable-stayed bridge system. The cable-stayed bridge comprises bridge towers, stay cables, main beams, side piers, middle piers, back cables and inhaul cables, and relates to the technical field of bridge engineering, wherein the bridge tower is designed to be arc-shaped; two ends of the back cable are respectively anchored at the top of the bridge tower; one end of the inhaul cable is connected with the back cable; the other end is anchored at the root of the bridge tower; the bridge towers, the back cables and the inhaul cables form a three-dimensional frame structure; the space rigidity of the cable-stayed bridge can be improved; the effect of resisting dead load and live load is facilitated; the back cable can be tensioned at the tower top for cable force adjustment; the inhaul cable can be tensioned at the root of the bridge tower for cable force adjustment; therefore, the stress state of the bridge tower under the action of deadweight and tension of the stay cable is improved; therefore, the line shape of the bridge tower is close to the reasonable arch axis, the bending moment borne by the root of the bridge tower is reduced, that is, the size of the cross section of the tower bottom does not need to be designed to be very large, and therefore the spanning capacity of the cable-stayed bridge can be enhanced, material loss and cost can be reduced, and the aesthetic feeling of the bridge can be enhanced.
本申请涉及一种海鸥式空间背索斜拉桥体系，包括桥塔、斜拉索、主梁、边墩、中墩、背索和拉索，涉及桥梁工程技术领域，其中，桥塔设计为弧线形，背索的两端分别锚固于桥塔顶部，且拉索一端与背索连接，另一端锚固于桥塔根部，使桥塔、背索和拉索形成了立体框架结构，其可提高斜拉桥的空间刚度，有利于抵抗恒载和活载的作用，且背索可在塔顶处张拉进行索力调整，而拉索可在桥塔根部处张拉进行索力调整，以改善桥塔在自重和斜拉索的拉力作用下的受力状态，进而使桥塔线形贴近合理的拱轴线，减小了桥塔根部所受到的弯矩，即无需将塔底的横截面尺寸设计的非常大，因此，本申请不仅可增强斜拉桥的跨越能力，降低材料的损耗和成本，还可增强桥梁的美感。
