Prerequisite or corequisite units are presented within each program

Learning unit contents

During this course, fist the concepts of soil mechanics will be presented. In the following, they will be used for the design and computation of earth structures. The course will deal with the following subjects :  

  • Soil mechanics: introduction, granular media, physical properties, classification, water in soils, seepage, soil - water interaction, mechanical properties, in situ stress state
  • Slope stability
  • Retaining structures : gravity walls, sheet piles
  • Shallow foundations, deep foundations
The course combines parts exposed by the teacher and the sessions of practical class under the shape of exercises. A visit of the laboratory of geotechnics is also organized to allow the students to confront and to complete their theoretical experiences with practical demonstrations of realization of the main soil tests realized in laboratory and in situ. A visit of construction site in connection with one or several geotechnical works is also organized.

Learning outcomes of the learning unit

In the term of course, the student will master the fundamental principles and the laws of the soil mechanics. He will be capable of choosing the tests of physical and mechanical characterizations suited to answer a given problem. He will be also capable of interpreting them and of applying them to the sizing of the foundations, retaining structure, slopes and earth dikes. After completing the course the student is expected to


  • Chose a geotechnical testing campaign
  • Interpret the main field and laboratory tests
  • Understand the principles of the main constitutive laws for soils
  • Calculate stress distribution under applied loads
  • Design a foundations for bearing capacity (ULS) and settlement (SLS)
  • Design soil retaining structures (walls, sheet piles, bracing)
  • Verify stability and safety of natural and manmade slopes

Prerequisite knowledge and skills

Solid mechanics

Planned learning activities and teaching methods

The theoretical course bases on presentations ex--cathédra. The notions seen in the theoretical course are illustrated through practical class, under the shape of exercises to be solved by the student by means of managerial employees. These sessions take place in room. additional exercices are proposed on the course eCampus website. A visit of the laboratory of geotechnics and a visit of construction site are also organized. The sessions of exercises and the visits are intended to facilitate the student to master the subject. The presence in practical class is compulsory.   To help the student to autoévaluer in the course of four-month period on the subject seen in the course, interrogations can be organized by the teacher. This interrogation will concern then the subject seen in the sessions of practical class, going to the week preceding the test. It will be announced at the latest two weeks before the date of the event. The quotation obtained in this interrogation could be taken into account in the calculation of the final quotation.

Mode of delivery (face to face, distance learning, hybrid learning)

Course given face-to-face during the 2nd semester, monday morning

Organisational adjustments related to the current health context

Recommended or required readings

Lectures notes are avalaible at student centrale des cours - AEES. All the pdf file and the slides used for the theoretical course are available on MyULiege and on eCampus.

Assessment methods and criteria

Below you will find information on the evaluation methods planned for in-person and remote exams as well as those planned for hybrid sessions. Depending on how the health crisis evolves, the chosen method will be communicated to you no later than one month before the start of the exam session.

Any session :

- In-person

written exam ( open-ended questions )

- Remote

written exam ( open-ended questions )

- If evaluation in "hybrid"

preferred in-person


Additional information:

Written exam on theory and exercices. In case of a reported session in September, no partial dispense will be available.
Option 1: exam on theory and exercises on all subject matter in June ; rating 50% + 50%. Effect of the March surveys 10% if favourable, 0% otherwise.
Option 2: 4 assesments (volume 1 + foundations) * (theory + exercises) + an examination (supports and slopes) (theory + exercises); Side work in slope stability , Rating = 4 quizzes * 10% + 1 exercise rated 10% + theory exam * 25% + exercise 20% + exercise red thread and participation 5%
The choice to take the full exam in June remains possible until the day before the exam.
 
 

Work placement(s)

Organizational remarks

During the sessions of practical class, the student will have to arm himself with a calculator, with a ruler capable of measuring angles and with a compass.
