摘　　要：建立了将围岩质量由原普氏坚固性系数f值分级转化到现行规范下的BQ分级的方法,并获得了引滦入津隧洞围岩质量的BQ分级。该分级对于隧洞除险加固及管护具有十分重要的意义。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 tun- nel 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.
