Hybrid bridge structure and hybrid cable-stayed bridge
The invention is suitable for the field of bridge engineering, and provides a hybrid bridge structure and a hybrid cable-stayed bridge. The hybrid bridge structure comprises a steel box girder and a concrete beam, wherein the steel box girder includes steel beam top plates and steel beam bodies arranged at the bottoms of the steel beam top plates, at least two steel beam bodies are arranged at intervals, and grooves with downward openings are formed between every two adjacent steel beam bodies and the steel beam top plates; the concrete beam is connected with the steel box girder, and the steel box girder and the concrete beam form a bridge floor for passage; and a connecting box used for allowing the concrete beam to extend into and be connected with is arranged at the position, close tothe concrete beam, of the groove, and an opening is formed in the side, facing the concrete beam, of the connecting box. In the invention, the steel box girder and the concrete beam at a joint sectionare both whole-box sections so that a violent change of rigidity can be avoided, smooth transmission of stress between the steel box girder and the concrete beam is realized, and the safety of the whole structure of the whole bridge is improved.
本发明适用于桥梁工程领域，提供了一种混合桥梁结构及混合斜拉桥。上述混合桥梁结构，包括：钢箱梁，包括钢梁顶板和设置在所述钢梁顶板底部的钢梁体，所述钢梁体至少间隔设置有两个，相邻两个所述钢梁体和所述钢梁顶板之间形成有朝下开口的凹槽；混凝土梁，与所述钢箱梁相连，所述钢箱梁和所述混凝土梁形成用于通行的桥面；所述凹槽靠近于所述混凝土梁的位置处设置有用于供所述混凝土梁伸入连接的连接箱体，所述连接箱体朝向所述混凝土梁的一侧为开口。在本发明中，结合段处的钢箱梁和混凝土梁均为整箱断面，能够避免刚度的剧烈变化，实现两者间受力的顺畅传递，提升了整体桥梁整体结构的安全性。
