摘　　要：为了对水电工程截流方式、截流时段以及截流备料的选择提供技术指导,通过截流模型试验对杨房沟水电站工程主河床截流方案进行了论证。从导流隧洞泄洪能力角度出发,验证了出口水位对上游进口水位及分流量的影响程度;另外通过对不同工况下截流模型试验结果的分析,选出了最优方案,并从用料量、截流单宽功率及流速等方面论证了该方案的合理性。In order to provide technical guidance for the selection of river closure way, closure time and preparation of closure materials for Yangfanggou Hydropower Station, model test was carried out to verify the main fiver closure schemes. From the perspective of flood discharge capacity of diversion tunnel, the influence degree of water level at tunnel outlet on inlet water level and diversion flow was analyzed. Through the analysis of test results under different operation conditions, the rationality of the optimal scheme was verified from dumping consumption, fiver closure unit power and flow velocity.
