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 in 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 resistance performance of U-shape aqueduct and the dynamic performance is better under the effect of the fluctuating wind but smaller stiffness for U-shape aqueduct than that for the rectangular aqueduct with the same water flux.
