摘要
依据水闸的结构特点,采用框架计算模型,利用温克尔地基假设,弹簧模拟地基和两侧土的作用;运用直接滤频法(逆迭代法)计算水闸结构自振特性,编制有限元计算程序,以上海市新民水闸为实例进行分析计算,结果与实际状况吻合较好.
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.
