Course description and aims
Soils are important engineering materials with complex mechanical characteristics. Among various basic knowledges on the soils to understand such characteristics, the followings are explained in this class.
1. Formation of soil deposits, 2. Physical and chemical properties of soils, 3. Soil classification, 4. Soil investigation methods, 5. Stress in ground (Principle of Effective Stress), 6. Seepage in ground, 7. Compression and consolidation of clay, 8. Mechanical properties of compacted soils
Student learning outcomes
Infrastructures and lifelines are basic components in the built environment. Knowledge and deep insight on the ground are critical in the design, construction and maintenance of those structures. In this class the students study about the ground formed in huge time and space, especially about basics, such as, 1) creation of soils and formation of soil deposits, 2) basic physical properties of soils, 3) soil classification methods, 4) soil investigation methods, 5) stresses in ground, 6) theory of ground water seepage,7) compression and consolidation of clay, (8)mechanical properties of compacted soils.
Keywords
soil mechanics, basic physical properties of soils, soil classification, ground seepage, compression and consolidation, unsaturated soils, compaction
