Course Description : The term ground improvement and ground modification refer to the improvement in or modification to the Engineering properties of a soil that carried out at a site where the soil in the natural state doesn't possess properties that are acceptable to us for the proposed civil Engineering activities.
The improved or modified soil exhibits satisfactory performance when foundations, earth structures, earth retaining structures and under ground structures are constructed on, within or using the soil.
The topics cover Engineering properties of soft, weak and compressible deposits, principles of treatment-loading (static and Dynamic), Accelerated flow, Reinforcement, Vertical drains, Granular piles, soil nailing, Anchors.
This course material on ground improvement technique will be very useful to undergraduate students, post-graduate students, teachers and practitioners and gain competence in properly devising alternative solutions to difficult and earth construction problems and in evaluating their effectiveness before, during and after construction.
A study of the many different approaches to the ground modification broadens the mind of any Engineer and inspires creativity and innovation in Geotechnical Construction and related fields.
A number of chosen field oriented problems will be solved to illustrate the concepts clearly.
Engineering properties of soft, weak and compressible deposits, principles of treatment-loading (static and Dynamic), Accelerated flow, Reinforcement, Drainage and filters, Injections, Thermal, electrical and Chemical Methods- Preloading, Dynamic Consolidation, Vertical drains, Granular piles, soil nailing, Anchors, Design Methods and Case histories.
To learn the various ground improvement methods with aid of theory
The students will be able to judge the appropriate ground improvement
technique need to apply with consideration of type of structure, soil
condition, environmental aspect and economy. They will be capable
enough to design the various ground improvement techniques
Course Outlines: Textbook chapters as announced, the following (recommended) Lecture Notes, and any other material the Instructor assigns.

Although instructor is free to make adjustments or modifications as circumstances permit.
Course Intended Learning Outcomes (ILOs) :
§ Dealing and using observance of soil improvement.
§ Assessment of soil behavior.
§ Development of research skills and presentation skills
Students are expected to read and follow the schedule in the course syllabus, to read assigned text chapters, to read assigned Lecture Notes, and to seek and read additional suggested resources as provided by the textbook and Instructor. In addition, students are expected to be alert and attentive with note taking in class and have a demonstrated desire to participate in any discussion. Exams are to be completed within the deadlines given by the Instructor, and any special instructions for the paper and/or writing assignment(s) are to be followed precisely. The Instructor will announce all deadlines and instructions as well as provide reminders about the pace or flow of the course.
ATTENDANCE POLICY: An attendance roster is kept (and login records, if this is a web-based course), and students are expected to attend all sessions on time and as scheduled. If a session and/or assignment deadline is to be missed for circumstances beyond the student's control, prior permission of the instructor must be obtained, and arrangements made for submission of the work. Regular late submission of work as well as tardiness and absenteeism will result in reduction of the final grade by at least one letter, depending upon severity. An "Incomplete" can only be given if the student has normally completed at least half the coursework, has a reasonable justification, and makes arrangements with the instructor.
Policies: Students are encouraged to discuss homeworks with their peers.
The above schedule and procedures are subject to change in the event of circumstances.
