Ultrahigh anti-seismic pier and ultrahigh anti-seismic bridge
The invention relates to the technical field of railway bridges, in particular to an ultrahigh anti-seismic pier and an ultrahigh anti-seismic bridge, the ultrahigh anti-seismic pier comprises a first pier column and a second pier column which are oppositely arranged, and a plurality of cross beams are arranged between the first pier column and the second pier column at intervals; an anti-buckling cross beam is also arranged between the upper part of the first pier column and the upper part of the second pier column, is positioned above all the cross beams, and is used for buffering relative deviation between the upper part of the first pier column and the upper part of the second pier column; relative offset between the upper portion of the first pier column and the upper portion of the second pier column under the action of an earthquake is buffered through the buckling-restrained cross beam, the structural safety of the pier columns is effectively guaranteed, and the situation that the upper portion of the pier column is cracked due to relative offset under the action of the earthquake is avoided. And the situation that the pier column top cross beam is damaged under the earthquake action is effectively avoided, the integrity of the pier structure under the earthquake action is guaranteed, and active protection on the pier structure under the earthquake action is achieved.
本发明涉及铁路桥梁技术领域，特别涉及一种超高抗震桥墩及一种超高抗震桥梁，一种超高抗震桥墩，包括相对设置的第一墩柱和第二墩柱，第一墩柱和第二墩柱之间间隔设置多个横梁，第一墩柱上部和第二墩柱上部之间还设置有防屈曲横梁，防屈曲横梁位于所有横梁上方，防屈曲横梁用于缓冲第一墩柱上部和第二墩柱上部之间的相对偏移，通过防屈曲横梁来缓冲在地震作用下第一墩柱上部和第二墩柱上部之间的相对偏移，有效保证墩柱的结构安全，避免了墩柱上部因在地震作用下发生相对偏移而出现被拉裂的情况，也有效避免了墩柱顶横梁在地震作用下出现损坏的情况，保证了桥墩结构在地震作用下的完整性，实现在地震作用下对桥墩结构的主动防护。
