2. Objectives and learning outcomes
2.1 Objectives
The scope of the subject is to teach the students the basics of earthworks and retaining structures, such as different earth pressure theories, different retaining structure systems and their design rules, basics of design methods according to Eurocode 7, determination of characteristical values of soil properties in engineering practice, slope stability analysis, shear strength properties, different slip surface geometries, theoretical background of slope stability calculation methods. The student shall be familiar with quality control. Furthermore, the types, technologies and applicability limits of soil improvement, soil stabilization and dewatering will be presented.
