Abstract :
In this paper, the coupling responses of water and high bent-type aqueduct under wind loads were studied by the Arbitrary Lagrangian-Eulerian (ALE) method. The natural vibration characteristics and transversal displacement, stress, overturning force, overturning moment, and hydrodynamic pressure of water-aqueduct coupling system were comparatively analyzed under different conditions of water-depth, cross-section shape of aqueduct tank, and support bearing. The research results show that the isolated support changes the dynamic characteristics and reduces wind-resistant performance of U-shape aqueduct. Therefore, the dynamic performance is better under the effect of the uctuating wind; however, the stiffness for U-shape aqueduct is smaller than that for the rectangular aqueduct, with the same water uxes.
