摘　　要：近海工程基础附近的海流性质是该类工程设计的重要依据,本文提出近海波动与基础绕流的统一算法,将计算分成前后两个层次:先用浅水长波方程算出二维流动,然后以算得的压力和水平流速为上边界条件,用完整的N-S方程对流动进行三维计算。这对近海工程结构设计具有实际意义。The offshore engineering designing depends upon the sea-water erosion near its base seriously. In this paper, a joint computation method for offshore wave and base flow is put forward . The computation is divided into two steps: First, it computes the 2-D flow by using the Shallow Water Wave Equation, and then solves the N-S Equation in the specific region with the boundary parameters gotten from the upper step. This is of great practical significance for such engineering designing.
