1. The rock mass at a hydroelectric powerhouse project in Himachal Pradesh, India, consists of jointed quartz mica schist with aver¬age GSI of about 65 (Hoek and Brown, 1997). Triaxial tests on intact rock cores showed a. = 30 MPa and tni = 15.6.

a. Estimate the rock mass parameters mm, s and a.

b. Estimate C and of the rock mass.

c. Estimate the uniaxial compressive and tensile strengths of the rock mass.

2. Carry out a thorough literature review and summarise the empirical correlations relating RMR, Q and GSI, including the limitations of the specific correlations.
