The huge water contained in duct is the predominant feature of aqueduct bridge. In isolation design of aqueduct bridge, if isolating bearing with significant shear deformation are adopted, the duct-water coupled components may be excited by wave, which include more richer long period impulse due to the filter action of bearing, under earthquake. Thus, the large amplitude sloshing of water may occur. Because this tendency has been observed in experiment, it is important to study the characteristics of water dynamic response in aqueduct bridge under the condition of large amplitude sloshing. Based on typical rectangular duct sections, following researches are carried out. (1) Checking the computational model with existed experiment data. (2) The nonlinear characteristics of water dynamic response due to large amplitude sloshing are illustrated through the relationship of exciting wave amplitude and water dynamic response such as wave elevation of free surface, water dynamic pressure, overturning force and overturning moment.(3) The relationship between varying exciting frequency and water dynamic response are investigated. These researches can provide the basis of conceptions and method for selecting parameter of isolation design of aqueduct bridge.
