Conclusions

  1. 1.

    Equation (3) is recommended for determining the design value of the coefficient of strength fst of rock en masse.

     
  2. 2.

    In engineering-geologic reconnaissance practice, use should be made of the classification presented in Table 1, in order to gather data for changing over to the new index of soundness of rock en masse.
