Rock Mechanics and Tunneling

By Prof. Debarghya Chakraborty | IIT Kharagpur

Learners enrolled: 1100

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

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

Please check the form for more details on the cities where the exams will be held, the conditions you agree to when you fill the form etc.

CRITERIA TO GET A CERTIFICATE

Average assignment score = 25% of average of best 8 assignments out of the total 12 assignments given in the course.
Exam score = 75% of the proctored certification exam score out of 100

Final score = Average assignment score + Exam score

YOU WILL BE ELIGIBLE FOR A CERTIFICATE ONLY IF AVERAGE ASSIGNMENT SCORE >=10/25 AND EXAM SCORE >= 30/75. If one of the 2 criteria is not met, you will not get the certificate even if the Final score >= 40/100.

Certificate will have your name, photograph and the score in the final exam with the breakup.It will have the logos of NPTEL and IIT Kharagpur .It will be e-verifiable at nptel.ac.in/noc.

Only the e-certificate will be made available. Hard copies will not be dispatched.
