Course Name : GROUND IMPROVEMENT TECHNIQUES Course Code : 58001 Class : IV B. Tech II Semester Branch : Civil Engineering Year : 2015 – 2016 Course Faculty : Dr. Kavita Singh, Assistant professor
OBJECTIVES
1. This course covers important design and construction aspects associated with ground
improvement techniques including Vertical Drains, Lightweight Fills, Vibro-Compaction,
Dynamic Compaction, Stone Columns, Deep Soil Mixing, Column Supported Embankments,
MSE Walls and Reinforced Soil Slopes, Soil Nailing, and Grouting.
2. The goal of the course is to help participants determine the applicability and preliminary cost
analysis for techniques that could be employed to improve the ground to permit construction of
geotechnical facilities for transportation applications.
3. Participants will develop an appreciation for exploring and characterizing subsurface soil and
rock in the laboratory, as well as the requisite design parameters necessary to develop a
preliminary design and cost estimate. Instructors will discuss and summarize the advantages and
limitations of each method.
4. The course is designed to elicit maximum input from participants particularly regarding their
understanding of application criteria, the impact of geotechnical features on the long-term
performance, and contracting methods.
