Lab In-charge: Dr. Thushara Madanayaka
Appointed TO: Mr. PP Rajamanthri
Geotechnical Engineering is the specialty of Civil Engineering which deals with the properties
and behaviour of soil in engineering purposes. This is one of the core subject areas of the Civil Engineering degree programme offering at General Sir John Kotelawala Defence University. Geotechnical Engineering Laboratory contributes mainly for teaching activities, design project activities, and engineering research activities providing support in a wide range of specialized areas including testing of soil properties, soil characterization and stability analysis of the soil mass.
The lab tests that can be carried out at the Geotechnical Engineering Laboratory include Moisture Content Determination, Maximum and Minimum Dry Density Determination, Grain Size Analysis (Sieve Analysis), Determination of Consistency Limits and Indices, Determination of Field Density of Soil (Sand Replacement Method), Compaction Test (Standard Proctor Compaction), Permeability Test (Constant and Falling head), Consolidation Test, Direct Shear Test, and Unconfined Compression Test.
The laboratory is currently equipped with the following instruments to aid in undergraduate learning and engineering research:
