| Abstract: | A method of classifiedly converting the original Protodyakonov’sCoefficient f into BQ classification of the current standard is established herein，and then the BQ classification of the quality of the surrounding rock of the water conveyance tunnel from Luanhe River to Tianjin is obtained. This classification has an important significance for the risk-elimination and strengthening as well as the maintenance of the tunnel. |
