Structure and method for restraining rotation vibration of high bridge tower and long cantilever cable-stayed bridge
The invention relates to the technical field of bridge engineering, in particular to a structure and method for restraining rotation vibration of a high bridge tower and a long cantilever cable-stayed bridge, the structure comprises a hoop structure, main body supporting structures and a transverse connecting system, the hoop structure is arranged on the bridge tower in a sleeving mode, and the multiple main body supporting structures are arranged on the two sides, in the transverse bridge direction, of the hoop structure; the bottom of the main body supporting structure is fixed to a main beam, and one side of the main body supporting structure is fixed to the hoop structure. The adjacent main body supporting structures are connected through the transverse connecting systems. The hoop structure, the main body supporting structure and the transverse connecting system are additionally arranged on the high bridge tower and the long cantilever cable-stayed bridge, so that the main body supporting structure, the bridge tower and the main beam form a whole, the free length of the main beam in the rotation process of the cable-stayed bridge is greatly reduced, meanwhile, the overall rigidity of the cable-stayed bridge is increased, the structural vibration frequency is increased, and the stability of the cable-stayed bridge is improved. Therefore, the vibration amplitude of the high bridge tower and the long cantilever cable-stayed bridge in the rotating process is effectively reduced.
本发明涉及桥梁工程技术领域，具体涉及一种抑制高桥塔、长悬臂斜拉桥转体振动的结构及方法，包括抱箍结构、主体支撑结构以及横向连接系，所述抱箍结构套装于桥塔上，所述抱箍结构横桥向的两侧均布置多个所述主体支撑结构；所述主体支撑结构的底部固定于主梁上，一侧与所述抱箍结构固定；相邻的所述主体支撑结构之间通过所述横向连接系连接。本发明通过在高桥塔、长悬臂斜拉桥上增加抱箍结构、主体支撑结构以及横向连接系，使主体支撑结构与桥塔、主梁形成一个整体，使得斜拉桥转体过程中主梁的自由长度大大减小，同时增加了斜拉桥的整体刚度，增加了结构振动的频率，从而有效地减小高桥塔、长悬臂斜拉桥转体过程过程中的振动幅度。
