Half-through steel arch bridge system and construction and design method
The invention relates to a steel arch bridge, in particular to a half-through steel arch bridge system and a construction and design method.The half-through steel arch bridge system comprises a steel structure arch rib assembly and a main beam, the two ends of the main beam penetrate through the steel structure arch rib assembly, and a rigid connecting rod is fixedly connected between the arch upper portion assembly and the main beam; the lower end of the arch lower portion assembly is fixedly connected with an arch seat, and a rigid stand column is fixedly connected between the arch lower portion assembly and the main beam. According to the half-through type steel arch bridge system, the purpose of reducing the dead weight of the arch bridge is achieved through the steel structure arch rib assembly made of the steel structure material, the problem that the material strength is basically consumed by the dead weight is effectively solved, and the steel structure arch rib assembly is fixedly connected with the main beam; and the steel structure arch rib assembly is fixedly connected with the main beam through the rigid connecting rod and the rigid stand column, so that the half-through steel arch bridge system forms a full-consolidation system, and the requirement for the overall stability of the kilometer-scale span arch bridge is met.
本发明涉及一种钢拱桥，特别是一种中承式钢拱桥体系、施工及设计方法，其中中承式钢拱桥体系包括钢结构拱肋组件和主梁，主梁两端穿过钢结构拱肋组件，拱上部组件与主梁之间固定连接有刚性连接杆，拱下部组件的下端部固定连接有拱座，拱下部组件与主梁之间固定连接有刚性立柱。本申请的一种中承式钢拱桥体系，通过采用钢结构材料的钢结构拱肋组件来达到降低拱桥自重的目的，有效避免材料强度基本被自重消耗殆尽的问题，而且通过将钢结构拱肋组件与主梁之间固定连接，且钢结构拱肋组件与主梁之间通过刚性连接杆和刚性立柱固定连接，将中承式钢拱桥体系形成全固结体系，以满足千米级跨径拱桥的整体稳定性要求。
