Recommended optional programme components

Optionally, students can attend lectures, field trips and workshops that are offered to them during the semester.

Recommended or required reading

Not applicable.

Planned learning activities and teaching methods

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

Assesment methods and criteria linked to learning outcomes

Aims

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.

Specification of controlled education, way of implementation and compensation for absences

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