Soils and subsurface formations

ECTS Credits : 2

Duration: 21 hours


Semester : S7

Person(s) in charge :

Yann GUNZBURGER, Associate Professor,

Keywords : Geotechnic, Water, Collapse, Soil Résistance, rock slope stability

Prerequisites : Courses SGEOS7AC and SGEOS7AD, or equivalent coursework

Objective :

This course deals with the fundamentals of Geotechnics. This field studies the characteristics as well as the mechanical and hydromechanical behaviour of poorly consolidated land surface (“soils”) used as material or weight-bearing support in construction. The main points covered in this course focus on the role of water in soil (the phenomena of settlement and swelling) and the resistance properties of soil when submitted to natural or man-made loads. The genesis of soils (and more generally, surficial geologic deposits) will also be presented.
At the end of the course, students will be able to perform simple calculations for settlement, stability and the pre-dimensioning of surface or sub-surface structures, such as cut and fill earthworks. Such calculations apply to civil engineering (public works), extractive industries (mining, petroleum, quarrying, etc.) and natural hazards (landslides).


Program and content:

• Water in geomaterials
• Surficial geologic deposits in France
• Identification and classification of soils – clay minerals and their properties - Compaction
• Settlement and swelling
• Shear resistance of soils
• Stability of slopes
