Course description and aims
This course is the laboratory class focusing on the material property of soil and mechanical behaviour of geotechnical structures.
Soils are composed of soil grain, water, and air. The characteristics (i.e. compressibility, strength, and permeability) depend not only on inherent properties of soils but also on state of soils. In addition, theoretical solutions do not necessarily capture the actual behaviour of geotechnical structures. Therefore, it is important to know mechanical characteristics of soils and behaviour of geotechnical structures through experiments. The aim of this course is to obtain knowledge of physical and mechanical properties of soil through conducting various soil tests (compaction tests, permeability tests, various index tests, oedometer tests, shear tests) and to experience performance evaluation of shallow foundation through physical model test using geotechnical centrifuge.
Through this course, students are expected to cultivate the basis of civil engineering and to get an experience of the team management in engineering.
Student learning outcomes
By the end of this course, students will be able to:
1) Understand the influence of particle size distribution and water content on soil compaction and its mechanical consequences.
2) Understand the influences of void ratio on permeability of soil and basic mechanism of soil liquefaction.
3) Understand the important basic properties of clay for estimation of shear strength, such as the relationship between consolidation pressure and void ratio, concepts of the normally consolidated and overconsolidated states.
4) Understand the influences of void ratio and stress history on shear strength of soil.
5) Accumulate skill and knowledge for design of foundation through prediction of the bearing capacity of shallow foundation.

Competencies that will be developed
| ✔ Specialist skills | Intercultural skills | ✔ Communication skills | ✔ Critical thinking skills | ✔ Practical and/or problem-solving skills |
Class flow
Classes will be held in each separated groups. You should gather at the instructed room, and the understanding of the experiment contents and related matters are checked in advance of the experiment. Sometimes the understanding of the experiment is checked after the class. In every class, you are requested to submit a report.
