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)

Lectures, practical and laboratory classes, and written communication.

The assessment of the learning outcomes specified in clause 2.2. above and the evaluation of student performance occurs via tests.

Evaluation form	Abbreviation	Assessed learning outcomes
1. Midterm test	ZH1	A.1-A.2; B.1-B.2; C.3; D.1-D.2
2. Midterm test	ZH2	A.3; B.3; C.1-C.3; D.1-D.2
3. Midterm test	ZH3	A.4-A.5; B.4-B.5; C.3; D.1-D.2

A szorgalmi időszakban tartott értékelések pontos idejét, a házi feladatok ki- és beadási határidejét a "Részletes féléves ütemterv" tartalmazza, mely elérhető a tárgy honlapján.

Abbreviation	Score
ZH1	30%
ZH2	30%
ZH3	40%
Sum	100%

The midterm tests are failed if the sum points of the test are less than the 50% of the obtainable points.

In case of failing the retake there is a possibility for second retake of one midterm test – after the payment of the fee determinated in the regulation – in the supplementary period.
