摘　　要：在高坝引水式电站的导流洞导流工作结束后进行封堵的过程中,通常预埋放水钢管作为厂坝间的生态流量下泄口,并以导流洞内建水电站的方式同步解决其消能问题。文中就如何合理选择洞内水电站厂房布置型式进行了研究和论证,最终确定洞内机组纵向一列式厂房布置方案,并成功地应用在莲峰水电站。During the plugging of the diversion tunnel of diversion type hydro-power station with high dam, the steel discharge culvert is normally embedded as the outlet for the eeo-discharge between the dam and the powerhouse, and then a mini-hydopower station is built inside of the diversion tunnel to solve the problem from the energy dissaption. How to reasonably select the layout of the powerhouse inside of the tunnel is studied and demonstrated herein, and the longitudinal layout of two units in one queue for the generating units in the tunnel is finally determined, which is already successfully applied to the construction of Lianfeng Hydropower Station as well.
