The results shows that sloshing amplitude of the water in U-shape aqueduct is very significant; the vribration frequency of the aqueduct structure is reduced due to the existence of the water body, and then the response wave shape of the aqueduct body is changed relatively. This explains that the effect of the water in the aqueduct structure has great relationship with the spectrum dynamic properties of the input earthquake wave. Water in the aqueduct plays TLD damping when the frequency scale of the input earthquake wave includes the basic frequency of the aqueduct structure and the vibration frequency of the water in the aqueduct is closed to the the basic frequency of the aqueduct structure. Finally an approximate criterion is also put forward to adjudge when the aqueduct water plays TLD damping through judging mass ratio and frequency ratio, and gives the discriminate.
