| Outline and Purpose of the Course | This course deals with near-surface quaternary soft soil deposits that are the most important in the engineering sense. Physical properties and the mechanical characteristics of partially saturated and fully saturated soils are explained, and then various problems in terms of disaster prevention and infrastructure construction are discussed. | |||
| Course Goals |
The aim of this course is to understand engineering problems and their mechanical background in the following points: - Physical properties and mechanical characteristics of quaternary soft soil deposits and relevant engineering problems in terms of disaster prevention - Fundamentals of unsaturated soil mechanics and engineering problems of earth structures in terms of disaster prevention - Concepts of innovative underground foundations and structures and engineering problems during construction |
