Student has a knowledge of basic design elements of underground structures and principle methods of design and checking of primary lining of underground structures. Student will be acquainted with geotechnical investigation, with influence of geology into the underground structures layout and with classification of rocks for underground structures. Further on with introduction into the theory of rocky pressures, with tunel systems for different profiles, explosive works, excavation of shafts. Student will be able to check deformations of suface. Excavated underground structures and microtunelling.

Student must for success in the discipline know: Basic principles of geology, soil and rock mechanics, foundation engineering, geodesy, building materials, structural mechanics, elasticity and plasticity theory, basic principles of railway, road and water structures.

Not required.

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

Not applicable.

Teaching methods are standard. Interpretation of the lectures are supplemented with practical examples in practice. The work also includes individual assignment - project.

The credit must be met by participation in education and training programs from solved exercises.
The test evaluates two questions, with the addition of an assessment of the semester project.
