Organisation and examination

Teaching in the first semester, review in January

Units courses prerequisite and corequisite

Prerequisite or corequisite units are presented within each program

Learning unit contents

The 'Soil and rock mechanics' course is the logical complement for the basics thought in geotechnical courses in Bachelor grade. The three main parts of this course are :

• Rock mechanics
• Constitutive modelling for soils and rocks
• Tunnel: excavation, retaining, convergence.

Learning outcomes of the learning unit

Student have to gain competencies needed for the three main parts of the course:
Rock mechanics: Nature, origins and structure of rock materials; Classification of rock materials; Classification of rock mass; Water into the rock mass; Mechanical properties; In-situ stress state; Mechanical properties of rock joints.
Constitutive models for geomaterials: Fundamental properties of constitutive laws; Elastic models; Elasto-plastic formulation; Internal friction models; CamClay models.
Tunnel: General introduction of the convergence-confinement method, mechanical behaviour of retaining, equation of the convergence-confinement method (elastic and elasto-plastic medium)

Prerequisite knowledge and skills

GCIV0603-1 : Geotechnics

Planned learning activities and teaching methods

The course is composed of "ex-cathedra" lectures (30 hours) and exercises (30 hours). Exercise sessions related to the three parts of the course allow the students to better understand the theoretical concepts.

Mode of delivery (face-to-face ; distance-learning)

The lectures and exercises session are delivered face-to-face. The attendance to all lectures and exercices session is mandatory. 

Recommended or required readings

Lecture notes in french are available for the part 'Rock mechanics'. They are available on MyULg. Slides are also available for the parts Constitutive model and 'Tunnel'.

Assessment methods and criteria

Each lesson and practises are mandatory.
Students will be evaluated based on the project reports (weight 30%). An oral exam will be organized in January (without access to any course materials) on the theoretical part of the course (weight 70%).
In case of second session (September), the grade obtained for the project reports will be kept and the theoretical part will be only evaluated.

Work placement(s)

Organizational remarks

The course will be given on Thursday afternoon, from 13h30 to 17h30.
Each lesson (4 hours) will be divided into two parts: a theoretical lesson (2 hours) and practises (2 hours).
A visit of a site related to the course will be organized.
