Unequal-height pier bridge structure collaborative anti-seismic system in river valley area based on swinging bridge piers
The invention relates to a river valley region unequal-height pier bridge structure collaborative anti-seismic system based on a swinging pier, and belongs to the technical field of civil engineering seismic resistance. Comprising a bridge superstructure and a plurality of piers with different heights, the piers comprise high piers and short piers, the high piers are cast-in-place piers, the short piers are swing short piers, the upper ends and the lower ends of the swing short piers are provided with cover beams and bearing platforms respectively, and swing interfaces are arranged between the swing short piers and the cover beams and between the swing short piers and the bearing platforms; the swinging short pier further comprises prestressed tendons and energy consumption devices. The prestressed tendons vertically penetrate through the swinging short piers, and the two ends of the prestressed tendons are anchored in the cover beam and the bearing platform respectively; the energy consumption devices comprise the first energy consumption device, the second energy consumption device and the third energy consumption device. The first energy consumption devices are arranged on the left side and the right side of the upper end and the lower end of the swing short pier. The second energy consumption devices are located between the rows of swing short piers on the transverse straining beams. The third energy consumption device is located between the different bent frame swing short piers in the longitudinal bridge direction.
本发明涉及一种基于摇摆桥墩的河谷地区不等高墩桥梁结构协同抗震体系，属于土木工程抗震技术领域。包括桥梁上部结构和若干个不等高的桥墩，所述桥墩包括高桥墩和矮桥墩，所述高桥墩为现浇桥墩，所述矮桥墩为摇摆矮墩，摇摆矮墩上下端分别设置有盖梁以及承台，摇摆矮墩与盖梁以及承台间均设置有摇摆界面；所述摇摆矮墩还包括预应力筋以及耗能装置；所述预应力筋竖向贯穿摇摆矮墩，且两端分别锚固在盖梁以及承台内；所述耗能装置包括1号耗能装置、2号耗能装置以及3号耗能装置；所述1号耗能装置设置在摇摆矮墩上、下端的左、右两侧；所述2号耗能装置位于横系梁处每排摇摆矮墩之间；所述3号耗能装置位于纵桥向不同排架摇摆矮墩之间。
