摘　　要：由若干独立摇板组成的多单元造波机是实验室研究波浪及其与海洋工程结构物相互作用的重要设备。由于单元摇板宽度和波浪周期对斜向波浪模拟方向角的限制、斜向波浪模拟引起的杂波和三维短峰波浪模拟的有效实验区范围等,是影响多单元造波机波浪模拟质量的关键问题。通过对海洋深水池双边多单元造波机性能的分析,获得了波向角与规则波浪周期的关系,避免杂波产生的波浪周期范围和三维短峰波浪有效实验区的范围。分析结果对于海洋深水池高质量模拟波浪并为海洋工程结构物模型试验提供良好的波浪环境条件具有重要意义。Segmented wavemakers which consist of numerous individually programmed paddles have become important in the study of wave and its interaction with ocean engineering structure in ocean basin.There are some key problems affecting the simulation quality of segmented wavemakers greatly,including the limitation of the direction angle of oblique wave simulation induced by the width of each paddle and wave period,the generation of spurious waves and the effective test area of 3D short-crested wave.The following results are obtained through the analysis on the performance of two-sided segmented wavemakers：（1）The relationship between oblique wave angle and wave period;（2）Wave direction limitation to prevent spurious waves;（3）Effective test area of simulated 3D short-crested wave.The results are significant to high quality wave simulation and providing better wave environment conditions for model tests of various ocean engineering structures in deep ocean basin.
