摘　　要：在计算渡槽动力特性时,槽内水体对结构产生的影响是不容忽视的。针对南水北调中线工程中某渡槽结构,分别采用附加质量法和基于FSI系统的(ui-p)格式建立了渡槽数值分析模型,对其动力特性进行了分析。The influence of water in aqueduct on the construction cannot be ignored when calculating the aqueduct dynamic characteristics. With an aim at some aqueduct in South-to-North Water Diversion Middle Route Project, the numerical analysis model is established on the basis of the additional mass principle and the displacement- press format of the FSI system, and also, the dynamic characteristic are analyzed.
