摘　　要：应用一种平面迎风有限元与垂向隐式有限差分相结合的数值计算方法建立了三维潮流和潮流输沙数学模型，并分别与相应的理论公式进行了对比验证．将建立的模型对广西廉州湾水域进行了计算，与实测资料的对比分析表明模型的计算结果符合实际．A calculation pattern, which combines horizontal upwind finite element method with vertical implicit difference. istaken as our calculation procedure to set up 3-dimensional mathematical model of tidal motion and sediment transport in tidal current. By comparing with the relative theoretical formula, the results are satisfactory. The model mentioned above has been appliedto the water area of the I.ianzhou Bay, Zhuang Autonomous Region of Guangxi. On the basis of analysis and comparison with thefield data, it is shown clearly that the model calculation results are reasonable.
