摘　　要：基于严寒地区KLSK水利枢纽溢流表孔水工模型试验的研究,通过模型试验对溢流表孔的堰面曲线、斜坡、反弧段的设计体型进行验证,原设计体型设计合理。溢流表孔的泄流能力略小于设计泄流能力,沿线均为正压;挑流消能效果较好,冲涮坑离挑流鼻坎较远不会危及鼻坎的安全。该工程已安全运行9年,可为同类工程的建设提供借鉴。This paper is based on the cold region KLSK water conservancy overflow hole hydraulic model test research, through the model test of the overflow hole table weir surface curve, slope, the segmental arc shape is validated, the original shape is reasonable design. Overflow table hole slight- ly less than the design discharge capacity, discharge capacity are all along the positive pressure; Pick flow energy dissipation effect is better, washing pit from pick nose far away will not endanger the safety of the nasal camp. The project safe operation has 9 years, can provide reference for the construction of similar proiects.
