Abstract

The paper introduces the geological exploration, ground stresses measurement of a proposed unlined high pressure tunnel at Zhouning hydropower station. Three dimension linear elastic and elastoplastic finite element computation shows that the secondary state and the third order state of stress fields around the rock mass adjacent to the tunnel is of compression in nature, which makes unlined tunneling feasible.
