Oblique bridge tower with orthogonal steel-concrete composite structure
The invention discloses an oblique bridge tower of an orthogonal steel-concrete composite structure, and relates to the technical field of bridges, the oblique bridge tower of the orthogonal steel-concrete composite structure comprises an upper tower column, a lower tower column and a lower tower column, the lower tower column is of a steel shell and concrete combined structure, the lower tower column comprises a steel shell and a first partition plate arranged in the steel shell, the first partition plate divides an inner cavity of the steel shell into a midspan partition bin close to the midspan and a side span partition bin close to the side span, and concrete is poured into the side span partition bin; and the position of the first partition plate is configured to enable the concrete stress to be within a standard allowable range. The advantages of the concrete and the steel are fully utilized, the flexural capacity of the section can be effectively improved, and the force transmission structure of the main tower and the bearing platform is simplified; the section centroid of the lower tower column combination deviates towards the side span, the inclination angle of the section centroid shaft is reduced, the bending moment of the leaning tower can be effectively reduced, meanwhile, the outer contour of the lower tower column is consistent with that of the upper tower column, and the beautiful leaning tower modeling is guaranteed.
本申请公开了一种正交钢混组合结构倾斜桥塔，涉及桥梁技术领域，该正交钢混组合结构倾斜桥塔包括：上塔柱，其为钢箱结构；下塔柱，其为钢壳混凝土组合结构，上述下塔柱包括钢壳和设置于钢壳内的第一隔板，上述第一隔板将钢壳内腔分隔为靠近中跨的中跨隔仓和靠近边跨的边跨隔仓，上述边跨隔仓内灌注有混凝土；上述第一隔板的位置被配置为：使混凝土应力在规范允许范围内。本申请充分利用了混凝土和钢材两种材料的优势，能有效提高截面的抗弯承载力，简化主塔与承台的传力构造；下塔柱组合截面形心往边跨偏移，使截面形心轴倾角减小，可有效降低斜塔的弯矩，同时下塔柱外轮廓与上塔柱一致，保证优美的斜塔造型。
