Large-span concrete-filled steel tube arch bridge main arch structure and construction method
The invention discloses a large-span concrete-filled steel tube arch bridge main arch structure and a construction method. The main arch structure comprises a main chord member, the main chord membercomprises an upper chord member and a lower chord member, a web member structure is connected between the upper chord member and the lower chord member, and the web member structure comprises a firstweb member assembly and a second web member assembly; the first web member assembly is located on the arch foot section, and the second web member assembly is located on the arch body section. The first web member assembly comprises a first inclined web member and a first transverse web member which are connected, a triangular space is defined by the first inclined web member, the first transverseweb member and the corresponding main chord member, a stiffening splicing plate is arranged in the triangular space, a connecting hole is formed in the stiffening splicing plate, and a stiffening plate matched with the connecting hole in shape is arranged in the connecting hole. The second web member assembly is of a triangular structure. According to the web member structure, the overall transverse out-of-plane rigidity of the concrete filled steel tube main arch can be improved, the web member stability and shear rigidity can also be improved, and the local and overall stability of a full bridge is ensured.
本发明公开了一种大跨径钢管混凝土拱桥主拱结构及施工方法，主拱结构包括主弦杆，主弦杆包括上弦杆和下弦杆，上弦杆和下弦杆之间连接有腹杆结构，腹杆结构包括第一腹杆组件和第二腹杆组件；第一腹杆组件位于拱脚段，第二腹杆组件位于拱身段；第一腹杆组件包括相连接的第一斜腹杆和第一横腹杆，第一斜腹杆和第一横腹杆与对应的主弦杆围成三角空间，三角空间内设置有加劲拼接板，加劲拼接板内设置有连接孔，连接孔内设置有与连接孔形状相适配的加劲板，第二腹杆组件呈三角形结构。该腹杆结构能够提高钢管混凝土主拱的整体横向面外刚度，还可以提高腹杆稳定性和抗剪刚度，确保了全桥局部和整体的稳定性。
