COURS.

APERÇU

After participating in the course, you will be able to:

• Learn the principles of basic and advanced soil mechanics laboratory testing
• Analyse and interpret soil mechanics laboratory test results
• Determine geotechnical design parameters from laboratory tests
• Plan and select laboratory tests for geotechnical engineering projects

Description:
Soil mechanics laboratory testing and experimentation have now become an integral part of most construction projects for soil characterization, compaction control, seepage analysis, settlement analysis, design of foundations, retaining walls, dams, and slope stability.

This course will start with reviewing basic tests for determining soil index properties, including soil gradation, Atterberg limits, and hydrometer analysis.

This will be followed by an in-depth review of standard and modified Proctor compaction tests and hydraulic conductivity measurements. This course will then focus on measuring the compressibility and shear strength of soils using different experiments, including incremental-loading and constant rate of strain oedometer tests, direct shear tests, triaxial tests, and direct simple shear and ring shear tests. In addition to describing testing equipment and procedures, the interpretation of experimental results and their application to engineering design will be presented with working examples for each test.

The course will be based on ASTM standard methods whenever applicable.
