| Abstract: | Grade 2 Hydropower Station in Tian Sheng Bridge is a big diversion power station. Three diversion tunnels arranged horizontally are 9.68km in average length. The bad geological sections in No.3 diversion tunnel are 1926m in total length. The technical problems for the treatment of bad geological sections in the underground diversion tunnel are successfully solved by means of thick liner, high pressure grouting, hand excavating pile, arched bridge span and etc. |
