摘　　要：淠河总干渠渡槽工程是国内第一座大型钢桁架渡槽,目前国内外尚缺乏针对这一桥型的注水过程的动力响应的研究。基于VOF和有限元方法对渡槽注水过程及在这一过程中结构的动力响应进行数值模拟。首先使用VOF方法,对不同开闸高度下的渡槽充水过程进行了多相流模拟,然后将得到的结果以静力荷载和动力荷载的形式加载到结构之上,得到相应的结构响应并对比了两种方法得到的结果。The Pi River steel truss aqueduct project is the first large steel truss aqueduct in China. Research on water filling process of this kind aqueduct is insufficient. Based on VOF(Volume of Fluid) and FEM(finite element method), this paper conducts numerical simulation of the process of aqueduct water filling and the dynamic response of the structure during the process. Firstly, VOF method is used to simulate multiphase flow in the process of water filling at different gate opening heights, and then the results are transformed into two different load patterns: static load and dynamic load, which are applied to the structure to obtain the structural response. The results obtained by the two methods are compared.
