Cable-stayed bridge structure system capable of improving anti-seismic performance
The invention relates to the technical field of bridge engineering, and discloses a cable-stayed bridge structure system capable of improving anti-seismic performance, which comprises a main beam, a bridge abutment, a bridge tower and stay cables, the main beam is erected on the bridge abutment and penetrates through the bridge tower, the main beam and the bridge tower are connected through a plurality of pairs of stay cables, and the bridge abutment comprises an abutment body; a buffering and damping assembly acting in the length direction of the main beam and a limiting assembly acting in the width direction of the main beam are arranged between the platform body and the main beam. The buffering and damping assembly is arranged between the abutment body and the main beam, the earthquake acting force borne by the bridge tower can be effectively shared, after the abutment body participates in earthquake resistance, the tower bottom bending moment of the bridge tower is reduced under the earthquake action, the design difficulty of the bridge tower is reduced accordingly, the sectional size and the material consumption of the bridge tower are reduced, and the earthquake resistance of the cable-stayed bridge can be effectively improved.
本发明涉及桥梁工程技术领域，公开了一种提高抗震性能的斜拉桥结构体系，包括主梁、桥台、桥塔和斜拉索，主梁架设在桥台上且穿过桥塔，主梁与桥塔之间通过多对斜拉索连接，桥台包括台身，台身与主梁之间设置有沿主梁长度方向作用的缓冲减震组件和沿主梁宽度方向作用的限位组件。本发明在台身和主梁之间设置缓冲减震组件，能够有效分担桥塔承受的地震作用力，台身参与抗震后，桥塔在地震作用下塔底弯矩得以下降，桥塔设计难度随之降低，桥塔截面尺寸、材料用量得以减小，能够有效提高斜拉桥的抗震性能。
