Aims

Aim of this subject is to introduce theoretical and technological issues of earth constructions 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.
