As a regulating structure in waterway ,permeable six-sided tetrahedron frame groups are widely used in the process of the middle and lower reaches of Yangtze River waterway regulation with good results ,but there are damages in large areas . Therefore , through a flume generalized model test , diara body and the deformation characteristics of the frame groups were analyzed .The results indicate that under the same flow rate ,the diara inundated degree is not in di-rect proportion with the scouring damage of the beach body ;the bottom edges and both sides of the permeable frame groups are prone to displacement ;when the frame groups are applied in shoal regulations ,the length of the frame bars and the overall layout scheme should be optimized and verified .%四面六边体透水框架作为一种航道整治建筑物广泛应用于长江中下游航道整治过程中并取得了较好的效果，但也存在大面积损毁现象。为此，通过水槽概化模型试验，对四面六边体透水框架群守护心滩时滩体及透水框架群变形特点进行了分析，结果表明：相同流量下，并非心滩淹没程度越低，滩体冲刷破坏越严重；在框架群的下边缘和两侧透水框架易发生位移；透水框架群应用于浅滩整治工程时，框架杆件长度及总体布置方案应进行优化和论证。
