Large-span bridge adopting XIE structure
The invention belongs to the technical field of bridge structures, and particularly relates to a large-span bridge adopting an XIE structure, which comprises a truss and a support frame, the support frame is arranged at the lower part of the truss, and the upper part of the support frame is fixedly connected with the bottom of the truss; the supporting frame comprises a supporting column, a first inclined rod and a horizontal opposite-pull rod, wherein the first inclined rod and the horizontal opposite-pull rod are located on the two sides of the supporting column. The supporting column, the first inclined rod and the opposite-pull rod define a triangular frame. All-steel materials are adopted, and construction is convenient. The truss is of a double-layer structure and is high in stability and excellent in dynamic characteristic. The supporting frame can reduce the calculation span of the truss, and then the overall rigidity of the structure is improved; the supporting frame is provided with a triangular truss structure to improve the linear rigidity of components of the supporting frame, and the stability of the structure is further improved. On the basis of a traditional truss, the Hooke's law and the triangle stability principle are utilized, the calculation span of the structure is reduced, the linear rigidity of components and the overall rigidity of the structure are improved, the bearing capacity is high, and the steel consumption is small.
本发明属于桥梁结构技术领域，具体涉及一种采用XIE结构的大跨度桥梁，包括：桁架和支撑架，支撑架设置于桁架下部，且支撑架上部与桁架底部固接；支撑架包括支撑柱、位于所述支撑柱两侧的第一斜杆和水平对拉杆，支撑柱、第一斜杆、对拉杆相互围成三角形框架。本发明采用全钢材质，施工方便。桁架采用双层架构，稳定性高，动力特性优。支撑架可以减少桁架的计算跨度，进而提高结构的整体刚度；支撑架通过设置三角桁结构来提高自身构件的线刚度，进一步增加了结构的稳定性。本发明在传统桁架的基础上，利用胡克定律和三角形稳定性原理，减少了结构的计算跨度，提高了构件的线刚度和结构整体刚度，承载能力强，用钢量少。
