Rock Mechanics and Tunneling

By Prof. Debarghya Chakraborty | IIT Kharagpur

Learners enrolled: 822

ABOUT THE COURSE :
A good understanding about the mechanics behind the load transfer mechanism and the stability of different geotechnical structures constructed in/on the rocks becomes very much essential for the civil and mining engineers. On the other hand, the tunneling is a very efficient solution for the public transport as well as other underground transport systems. The course ‘Rock Mechanics and Tunneling’ will give an overall idea about the rock mechanics and its applications.

INTENDED AUDIENCE : B.Tech./B.E., M.Tech./M.E., Ph.D.

PRE REQUISITE :Engineering Mechanics, Solid Mechanics, Soil Mechanics

INDUSTRY SUPPORTED : Most of the Civil infrastructure development companies and the Companies dealing with the mining operations.
