The invention discloses a bridge engineering superstructure horizontal displacement restraint system which comprises a first restraint mechanism arranged at the center of a side pier and a second restraint mechanism arranged at the center of a middle pier, and the first restraint mechanism can move in the bridge direction in the horizontal direction and does not move in the transverse bridge direction in the horizontal direction; the second restraining mechanism does not move in the bridge direction in the horizontal direction and can move in the transverse bridge direction in the horizontal direction. The first restraining mechanism and the second restraining mechanism are the same in structure and comprise pin shafts, the lower portions of the pin shafts are anchored into the pier cover beam, and the upper portions of the pin shafts extend into the upper portion of the bridge. For a newly-built bridge or an old bridge adopting a plate-type rubber support, when the horizontal load transmitted from an upper structure cannot be effectively resisted only by virtue of the bonding force between the support and the upper structure, the restraint system provided by the invention can be adopted to limit the large relative displacement between the upper structure and the lower structure of the bridge, so that the bridge damage caused by the large relative displacement is avoided.
本发明公开了一种桥梁工程上部结构水平位移约束系统，包括布置在边墩中心处的第一约束机构和布置在中墩中心处的第二约束机构，所述第一约束机构水平方向顺桥向可动，水平方向横桥向不动；所述第二约束机构水平方向顺桥向不动，水平方向横桥向可动。所述第一约束机构与第二约束机构结构相同，均包括销轴，所述销轴下部锚入桥墩盖梁，销轴上部伸入桥梁上部。对于采用板式橡胶支座新建桥梁或旧桥，当仅靠支座与上部结构的粘结力不能有效抵抗上部结构传来的水平荷载时，可采用本发明提供的约束系统限制桥梁上下部结构之间产生较大的相对位移，避免由此引起的桥梁病害。
