2. Objectives and learning outcomes
2.1 Objectives
The scope of the subject is to teach the students the followings: fundamentals of geotechnics, origin of soils, types of soil exploration and soil samples, composition of soils (phase relationships), soil classification (particle size distribution, Atterberg limits) and compaction of soils. After the course the student is able to calculate vertical stress distribution in soil masses (with and without seepage), seepage in soils (Darcy’s law, hydraulic gradient, coefficient of permeability) and gets know the relationships of soil compressibility (primary consolidation, secondary compression) and the shear strength of soils (Mohr-Coulomb failure criterion, determination shear strength parameters)
2.2 Learning outcomes
Upon successful completion of this subject, the student:
A. Knowledge
  1. knows the phase relationships of soils,
  2. knows the soils classification procedures and the corresponding laboratory tests,
  3. knows the seepage relationships,
  4. knows the deformation characteristics of soils,
  5. knows the shear strength parameters of soils.
B. Skills
  1. is able to evaluate the basic geotechnical laboratory results,
  2. is able to classify the soil based laboratory test results,
  3. is able to solve simple one dimensional water flow problems,
  4. is able to calculate soil compression for simple problems,
  5. is able to determine shear strength parameters of soils.
C. Attitudes
  1. is cooperative with the teacher in gaining new knowledge,
  2. is continuously expanding his/her knowledge through learning,
  3. strives for accurate task solving
D. Autonomy and Responsibility
  1. individually assesses geotechnical problems, as well as their solution based on given sources
  2. applies a systematic way of thinking
2.3 Methods
Lectures, practical and laboratory classes, and written communication.
