Goals
Furnish the student with detailed knowledge of clay mineralogy, the diffuse double layer theory and the
factors influencing the DDL thickness. Conduct soil stabilization with various types of additives. Identify
and stabilize problematic soils such as collapsing soils, dispersive soils, and expansive soils. Design
foundations on swelling/shrinking soils including underreamed pile foundations. Design preloading to
reduce soil compressibility. Design reinforced earth retaining walls. Implementation of the EK principle
for soil remediation.
Learning
Outcomes:
After successfully completing this course, the students should be able to:
1. Comprehend the principles of clay mineralogy and their influence on soil behavior.
2. Perform soil stabilization with or without additives in accordance with the nature of the problem at hand.
3. Identify and stabilize collapsing soils.
4. Identify and stabilize dispersive soils.
5. Identify, stabilize, predict soil heave, and method of treating expansive soils and best foundation type of
the situation to be dealt with.
6. Design and perform preloading to improve highly compressible soils.
7. Design reinforced earth retaining walls and reinforced earthdams.
8. Design system of vertical sand drains to meet the requirement of time and settlement.
9. Comprehend the principles of electrokinetic processes and apply them to remediate contaminated sites
