摘　　要：无论是水库中的溢流堰还是河道修建拦洪闸,都可采用迷宫堰这一新型结构。介绍了迷宫堰几何形状特征,运用量纲分析π定理方法,定性分析了泄流量函数关系式及影响流量系数的物理因素。在归纳了迷宫堰尚存在待进一步细化和深化的问题的同时,预测了迷宫堰推广应用前景。Both the overflow dam in the reservoir and the barrage constructed in the channel could adopt the newly- construtted labyrinth weir. Through ,Л- theorem of dimensional analysis, this passage outlines the geometry character of labyrinth weir, analyzes discharge functional relationship as well as some physical factors influencing coefficient of discharge, summarizes the existent problems that need further deepening analysis of labyrinth weir.
