Which type of failure is common in heavily jointed rock masses?
A. Tensile failure
B. Slabbing
C. Blocky failure
D. Compressive failure
Answer: Option C
Solution (By Examveda Team)
In jointed rocks, blocky failure occurs due to the movement of rock blocks along joints or discontinuities.This contrasts with intact rock failure.This Question Belongs to Geological Engineering >> Rock Mechanics And Rock Engineering
