摘　　要：本文是在连云港整体物理模型试验的基础上,按照潮波能谱模式进行全港区二维潮流计算。本模式在空间上采用有限元法求解能谱控制方程中的水位,进而求得各分潮的水位和流速值。通过叠加求得任意时刻的水位、流速的瞬时值。该方法简捷、有效,适应性强。通过连云港西大堤工程的兴建与不建两种情况的计算,所得结果与物理模型试验结果进行了比较。证明该方法是成功的。On the basis of entire physical model tests for Lianyun Harbor, this paper has described the two-dimensional tidal current calculation for the whole harbor according to the mode of the tidal wave spectrum,From energy spectrum control equation the elevaton of water can be specially obtained by the aid of the method of finite element and the elevations of water and velocity of various tidal constitutent can be further obtained, The instantaneous values of wale'r level and valocity during arbitrary period can be estimated after iterative solution. This method has same advantage of easy, efficient and is of great adaptability. Two cases with andwithout construction of the western embankment located in Lianyun Harbor were estimated and the estimated results have been compared with results form model te-. sts. The comparison shows that the method is seccessf ul.
