摘　　要：利用实测的钱塘江地形数据建立了钱塘江三维河道的计算机几何模型,并根据已有的涨潮潮位等水文信息,采用VOF方法追踪模拟水和大气的自由交界表面,对钱塘江涌潮进行了三维非稳态数值模拟。数值模拟结果与不同时刻和不同测点所测得的水文数据的对比显示,模型能较好地模拟涨潮条件下河道内流场和潮位的变化。在此基础上进行了涌潮对河道内流场影响的规律的研究。A three-dimensional geometric model was built according to the measured terrain data of Qiantang River. The three-dimensional numerical simulation of tidal bore was carried out and the VOF model was used to track the free surface of water and flow when seawater was intruded in. The numerical results of the tidal water level fit well with the measured hydrological data. Then the influence of the tide on the flow field in the river was investigated
