چکیده
|
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.
