Course Objective

The purpose of this course is to inform the students about the subject of the ground improvement, which has an important place in Geotechnical Engineering. In this way, the course aims to present the techniques for the improvement of the soil bearing capacity and to guide the students for the selection of the appropriate ground improvement technique, which they may be faced in practice.

Learning Outcomes of the Course Unit

1	To detect the ground problems in terms of Geotechnical Engineering view.
2	To select the appropriate improvement technique intended to the solution of ground problems.
3	To compare the ground improvement techniques in it self.
4	To test the ground improvement techniques in the laboratory at small scales.
5	To associate the test results with the insitu performance.
6	To determine the appropriate ground improvement technique for the solution of the ground problems.

Mode of Delivery

Planned Learning Activities and Teaching Methods

The courses will be conducted in the class and will be supported by presentations. The students will be informed about the topics before the class, so they will have brief information about each week s topic. Three laboratory works will be performed in course period in order to represent the some of the ground improvement techniques in laboratory. The reports and presentation of the laboratory work will be presented by the students.
