The presented topic is practiced on a project involving the individually discussed. Part of the exercise takes place in a classroom PC - application software for the solution of the problem. Work is in a group of two or three people. Project is closed oral presentations. Technological procedures are presented in the form of short videos. Textbooks are available in electronic form, including references to the literature.

For successful completion of the course must meet the following conditions:
1st. The credit.
1.1 Conditions for obtaining credit - attendance, project submission, oral presentation of the project.
2nd. Passing exams.
2.1 Written examination (consisting of computational example and questions). In case of a tie result of the written examination followed by an oral part.

1. Introduction of Earth structures – types, basic features and geological investigation.
2. Material for Earth structures – soil
3. Material for Earth structures – rock material, recycled materials, light weight fills
4. Principles, aspects of area compaction and area stabilisation
5. General principles of designing earth structures – stability, settlements.
6. Ground improvement – Precompression, Vertical drains
7. Ground improvement – Deep Soil Mixing, Deep Dynamic Compaction
8. Ground improvement – Stone Columns
9. Geosynthetics - properties; separation, filtration, drainage and erosion function
10. Geosynthetics - reinforcement function
11. Gabions, Nails
12. Technology of Earth structures(embankment, cut-off)
13. Monitoring of Earth structures

Not applicable.

Aim of this subject is to introduce theoretical and technological issues of earth structures with special emphasis on traffic structures. Theoretical part of the subject introduces basic theoretical principles, design procedures of earth structures (stability, deformation, ground improvement) and their analysis.
Technological part is dedicated to the issues connected with execution of the earth structures. It discusses construction requirements, ground improvement techniques and others.
Students will continuously verify gained knowledge on Seminars by manual calculations as well as by calculations supported by specialized software.

Extent and forms are specified by guarantor’s regulation updated for every academic year.
