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.}, keywords = {high bent-type aqueduct,fluctuating wind,wind-induced response,water-aqueduct coupling system,ALE method}, url = {https://scientiairanica.sharif.edu/article_4531.html}, eprint = {https://scientiairanica.sharif.edu/article_4531_7483da16edab09fa478789cfb4411c0b.pdf} }
