Longitudinal anti-seismic stop block for flexible pier bridge and design method
The invention relates to the technical field of bridge seismic resistance, in particular to a longitudinal anti-seismic stop block for a flexible pier bridge and a design method. The longitudinal anti-seismic stop block is installed between a transition pier cover beam and a main beam of the flexible pier bridge, and the longitudinal anti-seismic stop block comprises a steel box stop block, an anchor plate, an anchor bar and a rubber cushion block; the transition pier cover beam is connected with the steel box stop block through the anchor plate, or the anchor plate and the anchor bar; and the rubber cushion block is attached to the upper portion of the steel box check block. The longitudinal anti-seismic blocking part enables a transition pier to participate in earthquake resistance and consume earthquake energy under the action of a strong earthquake of the type of bridge, so that the bridge is ensured not to have a beam falling problem.
本发明涉及桥梁抗震技术领域，具体涉及到一种柔性墩桥梁纵向抗震挡块及设计方法；所述纵向抗震挡块安装于柔性墩桥梁的过渡桥墩盖梁和主梁之间，所述纵向抗震挡块包括：钢箱挡块、锚板、锚筋和橡胶垫块；过渡桥墩盖梁通过锚板或锚板与锚筋，与钢箱挡块连接；所述钢箱挡块上部贴有橡胶垫块。该纵向抗震阻挡部使该类型桥梁在强烈地震作用下过渡桥墩参与抵抗地震作用和消耗地震能量，保证桥梁不出现落梁问题。
