| 摘 要： | 针对辽东湾顶的复杂地形，本文使用有限元方法离散浅水波动方程。对计算区域采用三角单元剖分，对水位和流速用线性插值函数逼近，应用动边界技术模拟了潮滩随水位变化而干出或淹没，对传统的底摩擦公式进行了改进，从而解决了在计算很浅的水域时，可能出现的数值不稳定问题。本文的计算值与实测资料符合良好。

| Abstract: | Finite element method is used to scatter the shallow water equations for site-specific topograph of top of Liao Dong Bay. The exposure or submerging of shoal with water elevation are simulated by triangulation in the computational area, linear interpolation for water and velocity, and moving boundary technics. The traditional bottom friction formula is developed and unstability when computed extremely shallow water is resolved. The results of computation are good agreement with the observed data. |
