Abstract: The diversion tunnels of Jinping Ⅱ hydropower station are characterized as complicated engineering geological conditions, thick overburden, long length and large size in diameter, which make the tunnel project the largest hydro-tunnel group in the world. In this paper, based on preliminary analysis on the safety monitoring data during construction of the diversion tunnel No.1 , the characteristics of deformation, stress and seepage pressure were understood to evaluate safety behavior of the diversion tunnel No.1, and provide reliable technical support for safe construction of the diversion tunnels No.2-4.
