In this paper the outrush accidents during construction period of a hydroplant’s diversion tunnels and their main characteristics are introduced in brief. Then the reasons of outrush accidents are analyzed based on rock mass structure and hydrogeological conditions. At last the outrush scopes are forecasted simply according to the outrush data and surrounding rock mass geological conditions.
