 Welcome to course C330, Geotechnical Engineering 2. I am sure you are aware of my credentials, I am DNC professor in department of civil engineering IIT Bombay. I enjoy teaching this course in particular because this application of what we have discussed in Geotechnical Engineering 1 and the biggest challenge is how to utilize in this these concepts in solving day to day problems. What you will notice is that the Geotechnical Engineering 1 was more conceptual, fundamental oriented course and Geotechnical Engineering 2 would be mostly application oriented. A bigger part of the course would be dealing with the shear strength theory of soils and how to apply it in solving the problems which the society is facing. Some of the applications of shear strength theory would be stability analysis of retaining systems, slope stability, cuts, trenches and so on. I will not be dealing with the concepts of Geotechnical Engineering related to the foundations because that is a separate course which is offered by my colleagues. So welcome to this course and I hope you will enjoy this thoroughly, thank you.
