Site Investigation and Soil Laboratory testing

I. Summary

Determining engineering properties of soils are one of the most important processes for designing and analyzing geotechnical structures.  Thus, experimental approaches for ground condition are basic and indispensable subject for civil engineering.  This class deals with entire process of planning the site investigation, field testing, soil sampling and laboratory testing. Lecture provides all the methodologies based on related theory of soil mechanics, and by performing laboratory tests, students are used to soil testing, experience soil properties and reviews soil mechanics theory in more direct manner.
