摘　　要：驮英水库泄洪隧洞由施工导流隧洞改建而成,考虑到泄洪隧洞兼有水库放空功能和冲沙功用,因此泄洪隧洞兼具三洞合一的功能。水力学计算也考虑了导流隧洞、泄洪隧洞及放空隧洞的要求。泄洪隧洞运行时,水流条件较为复杂,因此建立了水库枢纽1∶80水工整体模型及1∶80施工导流整体模型进行水工模型试验,验证了泄洪隧洞设计的可行性。The original construction diversion tunnel of Tuoying Reservoir will be modified to become flood discharge tunnel incorporating with reservoir emptying and sand flushing,so the hydraulic calculation took into consideration the requirements of diversion tunnel,flood discharge tunnel and emptying tunnel.The flow conditions were relatively complex under flood discharge operation,so 1:80 integral hydraulic model test of the overall reservoir and 1:80 construction diversion integral model test were conducted,which verified the feasibility of flood discharge tunnel design.
