| Abstract: | Based on the structure of a sluice, the author chooses a frame structural model and uses the Winkle assumption. A spring model simulates the effects of the ground base on the soil stratum. A reverse iteration method is used to calculate the vibration frequency of the sluice structure. With finite (element) programming, the Xinming Sluice in Shanghai is calculated. The results are close to measurements. |
