摘　　要：迷宫堰相较于直线堰,最大的优越性体现在它的泄流能力上。通过模型试验,在分析迷宫堰的泄流形态的基础上,着重分析了堰墙与来流夹角α、水头比H0/P、平面布置形式、水舌通气等几个因素对迷宫堰泄流系数的影响。The labyrinth weir has the advantage of discharge capacity relative to that of the straight weir. Based on the flow shape analysis, the factors that influence the discharge coefficient of labyrinth weir were studied through experiments This study presents discharge coefficient data for labyrinth weir with weir height ratios H0/P and sidewall angle α in different conditions including different plane layouts and various nappe conditions （vented and non-vented）.
