Key words
Objectives
To provide a basic understanding of Soil Mechanics, i. e. the mechanical properties and behaviour of soils during geotechnical constructions, as building foundations, specially the know how of the design, calculation and control of shallow foundations.
Topics
• Introduction, historical background and description of soil: geological description – rocks – stone – gravel – sand – silt – loam – peat - …
• Geotechnical characteristics and classification of soils.
• Previous investigation, use of data, research the site in situ, soil testing and description of soils: grain-size distribution – density and compaction of sands – determination of the plastic limits – triaxial tests – CPT-tests – boring tests.
• Stresses and strains in soils: total and effective stresses and the effects of ground water pressure and consolidation.
• Shear strength of soil (labo- and in situ tests).
• Settlement criteria of soils (labo- and in situ tests).
• Shallow foundations: distribution of stresses in the plane between soil – foundation (base foundation surface).
• Shallow foundations: bearing capacity and settlement.
• Practical calculation of bearing capacity and settlement.
• Eurocode 7.
Prerequisites
Initial prerequisite: stabiliteit 1.
No specific prerequisites on soil mechanics.
Final Objectives
To provide a basic understanding of Soil Mechanics, i. e. the mechanical properties and behaviour of soils during forces from geotechnical constructions, as building foundations.
Starting from CPT (cone penetration tests) and the initial loads coming from the structures, design shallow foundations and control the bearing capacity and calculate the settlement.

Assessment
Oral examination based on the know how of design and calculation of shallow foundation. Individual exercises based on the results of CPT-tests (download on DOV).
A weighted average is used to compute the final score for a training item.
However, if a student gains a score of 7 or less on 20 on one of the different
courses (parts of training items) , he proves that his skill for certain
subcompetencies is insufficient. Consequently, one can turn from the arithmetical
calculation of the final assignment of quotas of a training item and the new
marks can be awarded on consensus.
Of course, the examiners can judge that the arithmetic regulations mentioned in
the study index card can also be used for 7 or less.
For each deviation a detailed motivation ought to be drawn up. In that case one
should point out that the skill for this subcompetency is proven to be
insufficient, if the student didn't pass the partim that is considered to be
important for certain subcompetencies.
