Abstract For the researching of the shear strength parameters of rock mass，the method proposed by this paper provides a new method and a new way. First，based on the deficiency of existing empirical formula，the mathematical relation between the geological strength index(GSI) and the basic quality index of rock mass(BQ)，the uniaxial compressive strength of saturated rock，the P-wave velocity of natural rock are established. For the rock masses uncovered by drilling，based on the results of borehole TV test，borehole ultrasonic velocity detection and laboratory core sample test，using the Hoek-Brown strength criterion，this paper puts forward a method for the estimation of rock shear strength parameters. Then this method is applied to a project under construction and the results show that the shear strength parameters of rock mass estimated by the method are close to actual values.

Key words： rock mechanics borehole TV rock mass ultrasonic velocity Hoek-Brown strength criterion shear strength of rock mass
