摘　　要：为研究STH水库底孔泄洪洞在校核工况下能否满足设计下泄流量,洞内水深能否满足净空要求,以及验证出口挑坎计算水舌长度;通过采用Ansys Fluent软件对校核工况下底孔泄洪洞进行三维数值模拟计算,对泄洪洞设计参数的合理性进行复核。The purpose of this paper is to study whether the bottom orifice flood discharge tunnel of STH reservoir can satisfy the designed discharge flow,whether the water depth in the tunnel can satisfy the clearance requirement,and to verify the calculated tongue length of outlet bucket under the check condition.Ansys Fluent software is used to carry out 3D numerical simulation calculation of bottom hole flood discharge tunnel under checked conditions,and the rationality of design parameters of flood discharge tunnel is checked.
