摘　　要：本文针对有限差分法在模拟潮流运动中遇到的边界问题 ,如岸边界问题、动边界问题和工程边界问题等 ,引入线边界的概念 ,并以此为研究对象 ,提出了较普遍适用的线边界法。实例应用分析表明 ,用线边界法处理各类边界问题 ,实用有效 ,简便易行。WT5”BZ]To deal with the problems of shore boundary, moving boundary and engineering boundary which appear frequently in the 2D tidal current simulation by the finite difference method, the concept of line boundary is introduced and studied here, then the line boundary technique in rather common use is proposed. Application and analysis of some calculation cases show that this technique is practical, effective, simple and feasible in 2D tidal current simulation when dealing with different boundary problems.
