Experimental Study on Seismic Isolation Bearing of Large Aqueduct

Though seismic isolation technology has been applied widely in civil engineering and proved effective, it is not used in large aqueduct. Shaking table test experiment was made on anti-seismic problem of a large aqueduct in South-to-north Water Transfer Project. First, a single span aqueduct model is designed and made. Then, several isolation bearings are designed for experiment. At last, the structure system dynamic responses were presented with isolation bearing mounted and not under different period earthquake loads for different working conditions. The results show that by using isolation bearings, which can play an important role in large aqueduct anti-seismic problem, the structure dynamic response can be reduced effectively.
