摘　　要：为了验证錾高水电站泄洪冲沙闸全开和局开、无闸溢流坝溢流等不同工况的过流能力、流态、下游冲刷及防冰凌等设计的合理性,通过对錾高水电站首部枢纽进行几何比尺为1∶50的水工模型试验,并对试验结果进行分析。结果表明:泄流能力满足设计要求;泄洪冲沙闸左侧边孔进口附近易出现强吸气旋涡,消力池出口冲刷较严重;将库水位抬升至1611.42 m可有效防冰凌。该模型试验可为下阶段的工程优化设计提供依据。In order to verify the rationality of the design of flow capacity,flow pattern,downstream erosion and anti-icing under different working conditions such as full opening and partial opening of flood discharge sluice,overflow of spillway dam without sluice in Zangao Hydropower Station,a hydraulic model test with a geometric scale of 1:50 is carried out on the head pivot of Zangao Hydropower Station,and the test results were analyzed.The results show that the discharge capacity meets the design requirements;The strong suction vortex is easy to appear near the inlet of the left side hole of the flood discharge sluice,and the scouring at the outlet of the stilling basin is more serious;Raising the reservoir water level to 1611.42 m can effectively prevent ice.The model test can provide basis for the engineering optimization design of the next stage.
