Shock absorption and isolation system and bridge
The invention relates to a shock absorption and isolation system and a bridge. The system comprise a bridge pier, a main beam arranged over the bridge pier; a first shock absorption and isolation mechanism connected between the bridge pier and the main beam and arranged in the transverse direction; and a second shock absorption and isolation mechanism connected between the main beam and the bridgepier and arranged in the longitudinal direction. The second shock absorption and isolation mechanism and the first shock absorption and isolation mechanism are arranged in an orthogonal mode. When anearthquake occurs in an external environment, the first shock absorption and isolation mechanism and the second shock absorption and isolation mechanism can work cooperatively at the same time; strong vibration generated by earthquakes is forcibly decomposed along respective movement directions; therefore, transverse and longitudinal motions are orthogonally separated to respectively reduce or eliminate the vibration in two different directions, the vibration damage of the earthquake to the bridge is greatly weakened, the shock absorption and shock resistance of the bridge are enhanced, and safe and reliable service of the bridge in an earthquake environment is guaranteed.
本发明涉及一种减隔震体系及桥梁，包括：桥墩；主梁，所述主梁间隔布置于所述桥墩的上方；第一减隔震机构，所述第一减隔震机构连接于所述桥墩与所述主梁之间并沿横向布置；及第二减隔震机构，所述第二减隔震机构连接于所述主梁与桥墩之间并沿纵向布置，且所述第二减隔震机构与所述第一减隔震机构呈正交布置。当外界环境发生地震时，第一减隔震机构和第二减隔震机构能够同时协同工作，将地震产生的强烈震动沿着各自的运动方向进行强制分解，即实现正交分离出横纵两种运动而分别减轻或消除两个不同方向上的震动，大大削弱了地震对桥梁造成的震动损害，加强了桥梁减震和抗震能力，进而利于保障桥梁在地震环境下安全可靠服役。
