Key words
piles – retaining walls – dams – slopes – global stability of constructions – soil pressure
Objectives
Introduction and overview of usual technics on different pile installations, retaining walls, dams and slopes, taking into account the particular requirements, to come to the most optimal choice in order of advantages and disadvantages of technique, financial impact and environment.
After his choice, the student is supposed to be able to detail the further design and calculation.
Topics
Piles:
- Introduction and overview of the Belgian pile installation practice.
- Material, dimensions and installation aspects of piles.
- The bearing capacity of a single axially loaded pile; design based on the result of in situ tests (CPT).
- Bearing capacity of group of piles: general quality behaviour.
- Control on the pile installation: static pile load test-execution – dynamic formulas - monitoring – measuring the impedance profile, the integrity of the installed pile.
Soil pressure and retaining walls:
Parameters and stability of soil – theoretical background based on the theory of the method of Coulomb - definitions: active, passive, neutral soil pressure – pressure/dept – influence of zero friction on the active and passive soil pressure.
Global stability of constructions:
Retaining walls and dams: control of bearing capacity and deformations - forces – practical examples - water after retaining walls – forces in the global stability of dams.
Stability of slopes:
General quality behaviour.
Retaining walls :
- sheet pile bulkheads - Berliner walls,…
- load and forces – overview of calculation methods - quality behaviour.
Prerequisites
See learning objectives under “berekening van construties 1”.

Assessment
Oral examination based on practical use of the knowledge of design and calculation of pile foundation, slopes, retaining walls and dams, sheet pile bulkheads.
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.
