Title: Selection of Discharge Tunnel Type of Buxi Hydropower Station on the Yazui River,Sichuan Province
Abstract: During the planning phase,the optimal and comparative selections were conducted for the discharge tunnel type.Based on referring to research document,on spot investigation,and hydraulic model test,it was convinced that the scheme of tunnel with vertical shaft combining with diversion tunnel could replace the primary one,which was side weir and raising head tunnel combining with diversion tunnel.The new scheme had a lot of advantages,such as high efficiency of energy dissipation,which means large proportion of energy was dissipated in the vertical shaft and flow path,and flexible arrangement,large discharge flow rate,easy to construction,high operation safety,and low investment.
