Abstract

Aiming at lack study for mechanical parameters of cataclastic rock mass in sliding zone of Daguangbao landslide，a new method for obtaining mechanical parameters of rock mass is proposed based on the improved Hoek-Brown criterion. Firstly，the value of geological strength index GSI should be quantized by rock mass basic quality index BQ，surface rating SR，surface condition rate SCR and joint condition factor J_c. On this basis，an improved formula of disturbance factor D through rock mass basic quality index BQ was established. By field investigation and laboratory test of rock mechanics，the improved method is substituted into Hoek-brown criterion，and then the mechanical parameters of cataclastic rock mass in sliding zone of Daguangbao landslide is evaluated. Compared with the E. Hoek method，the mechanical parameters of rock mass obtained by the improved method are relatively small，which is closed to the previous suggestions. It proved that this method has a definite rationality.

Key words： slope engineering Daguangbao landslide cataclastic rock mass mechanical strength parameters of rock mass Hoek-Brown criterion
