Rock Engineering

This course is the basic course in the area of Rock Mechanics. This will provide the knowledge of overall behavior of rocks and rock masses. This course will enable the students to acquire basics of analysis and design of tunnels, caverns, slopes, and foundations on rocks.INTENDED AUDIENCE :NonePREREQUISITES : Soil Mechanics-1, Soil Mechanics-2INDUSTRIES SUPPORT :This is the basic course in the area of Rock Mechanics and Rock Engineering. This will provide knowledge of analysis and design of tunnels, caverns, slopes and foundations on rocks. Industries involved with infrastructure development in hilly terrain and mining shall recognize /value this course.
