GEOTECHNICAL ENGINEERING
INTRODUCTION
SYNOPSIS
• This course deals with the principles of geotechnical analysis and design approach related to the two dimensional flow in soil, retaining structures, ground improvement and slope risk assessment analysis for civil engineering purposes.
INTRODUCTION
COURSE OUTCOMES
At the end of this course, the students should be able:
a. Understand and analyse seepage theory in 2-D flowproblems associated with the construction of dam.
b. Conduct slope risk assessment analysis, slopeprotection and rehabilitation works.
c. Analysis and design retaining structures, reinforced earth structures and cofferdams.
d. Understand the various methods of ground improvement techniques under different soil conditions.
