Analysis and Evaluation on the Diversion Tunnel Monitoring of Gongboxia Hydropower Station

The blocking of section 0+159 m-I.0+214 m has been implemented one month after the diversion tunnel of Gongboxia Hydropower Station started to impound.However,the downstream of the section 0+214 m has been changed into the right bank of cyclone spillway section under the adit,the swirling flow of holes,water plunge pool and the back water tunnel.So,the security of the sections down the section 0+214 m directly affects flood discharge of the barilleri.This paper will have a comprehensive analysis,research,and evaluation for monitoring data on 4 monitoring sections below the body of Gongboxia Hydropower Station 0+214 m diversion tunnel.
