Multi-section energy dissipation horizontal swing pier
The invention relates to the field of bridge engineering, and particularly discloses a multi-section type energy dissipation horizontal swing pier which comprises a support and a pier body. The pier body comprises a supporting pier and a plurality of subsection piers, the supporting pier and the subsection piers are hollow structures, and the lowermost subsection pier is fixedly connected with thesupporting pier. A circular ladder groove is formed in the upper end of each subsection pier, a cylindrical limiting cylinder is arranged at the lower end of each subsection pier, the diameter of each limiting cylinder is smaller than the inner diameter of the corresponding circular ladder groove, the subsection piers are overlapped up and down, and the uppermost subsection pier can support the support. The invention aims to solve the technical problem that an existing ductile design causes more serious damage to the bridge under the action of a strong earthquake.
本发明涉及桥梁工程领域，具体公开了多段式耗能水平摇摆桥墩，包括支座和桥墩本体，所述桥墩本体包括支撑桥墩和若干分段桥墩，所述支撑桥墩和分段桥墩均为中空结构，最下方的分段桥墩与支撑桥墩固定连接，所述分段桥墩的上端设有圆形梯槽，所述分段桥墩的下端设有筒状的限位筒，所述限位筒的直径小于圆形梯槽的内径，若干分段桥墩上下重叠，最上方的分段桥墩能够支撑支座。本发明的目的在于解决现有的延性设计在强震作用下导致桥梁受损更加严重的技术问题。
