Period II
Language ENG

Prerequisites
Basic concepts of soil mechanics

Learning outcomes
KNOWLEDGE AND UNDERSTANDING:
The course will provide a specific knowledge of a range of ground improvement techniques for both fine-grained and coarse-grained soils; the student learns the principles behind how the techniques 'work', for which soils they are appropriate and how they are installed or constructed.
CAPACITY TO APPLY KNOWLEDGE AND UNDERSTANDING:
The student will be able to select for each improvement technique the range of application as well as advantages and possible drawbacks. In such a way for a range of ground and site conditions the method that allows to optimise the cost/benefit ratio will be individuated.
TRANSVERSAL SKILLS:
During the course students are encouraged to study some topics in groups, in order to improve their single autonomous assessment, communication skills and learning ability.

Program
Classifications of soil improvement techniques. Relative density of sands. Soil liquefaction. Vibro-compaction. Heavy tamping. Preloading. Vertical drains. Drainage trenches. Stone columns. Reinforced earth. Grouting. Ground anchors. Freezing. Passive piles. Deep mixing. Soil-Lime and soil-cement mixtures.

Development of the examination
LEARNING EVALUATION METHODS
Oral test.

LEARNING EVALUATION CRITERIA
To positively pass the exam, the student has to demonstrate to be well acquainted with both theoretical concepts and use of the applicative tools of the Soil Improvement.

LEARNING MEASUREMENT CRITERIA
Final mark, in thirtieths.

FINAL MARK ALLOCATION CRITERIA
The oral test consists of three questions. Each question will be marked between 0 and 10 points. Honours will be given to those students who, reaching the highest marks, demonstrate a full mastery of the topics.
