The program in geotechnical engineering emphasizes advanced study and research in the areas of soil dynamics, ground improvement, problems of dynamic soil-structure interaction, numerical modeling of soil and foundation systems, and soil exploration using seismic methods. Also special emphasis is given to transportation problems, in particular pavement materials, design and management. Department provides a focus for each student's program through course work and research in geotechnical, transportation materials and infrastructure evaluation engineering projects.
