摘　　要：该文以某典型岛礁地形为研究对象,通过水池模型试验方法对岛礁附近波浪沿程变化、横剖面波高变化和礁坪上波浪变化等近岛礁波浪传播变形特征进行了分析。研究结果表明,波浪从远海传播至岛礁附近,经过礁坪前地形剧烈变化地带时波高增大后迅速减小,并在礁坪边缘与浅水礁坪的衔接段形成破碎带,最后进入浅水礁坪后波高基本由水深控制。A typical island is taken as the research object in this paper. The wave propagation characteristics near island such as wave variation along island, wave height changes in the cross-section of island and wave transform on the reef flat etc are analyzed by model test. The research results show that the wave height increases before reef flat and then decrease rapidly with the terrain changing fiercely, and a wave breaking zone will be formed in the convergence section between the edge and shallow water area of reef flat, the wave height will be controlled by the water depth at last. The analysis results can provide a reference for the programming and design of subsequent projects near island.
