摘　　要：通过水槽概化模型试验,对比分析有无护滩建筑物时四面六边透水框架附近的水流结构,给出了四面六边体透水框架周围纵向和横向水面线的趋势以及周围流速的变化,得出"四面六边体透水框架具有较好的护滩效果"的结论。The tendency of longitudinal and lateral water surface profile and change of velocity near the triangular taper penetrating frame are given by the flume generalized model experiment and through comparison between with and without the flow structure near the triangular taper penetrating frame with beach protection construction.The conclusion that＂ the triangular taper penetrating frame can protect better the beach＂ is drawn.

关 键 词：四面六边透水框架 水流结构 水槽试验
