Course Objectives:
This course will enable students
- To appreciate basic concepts of soil mechanics as an integral part in the knowledge of civil engineering. Also to become familiar broadly with geotechnical engineering problems such as, foundation engineering, flow of water through soil medium and terminologies associated with geotechnical engineering.
- To know the basic engineering properties and the mechanical behaviour of different types of soil. This includes strength-deformation characteristics under shearing stresses. Also consolidation properties of clayey soils.
- To determine the improvement in mechanical behaviour by densification of soil deposits using compaction.
- To know how the properties of soils that can be measured in the lab

Course Outcomes:
On the completion of this course students are expected to attain the following outcomes;
- Will acquire an understanding of the procedures to determine index properties of any type of soil, classify the soil based on its index properties
- Will be able to determine compaction characteristics of soil and apply that knowledge to assess field compaction procedures
- Will be able to determine permeability property of soils and acquires conceptual knowledge about stresses due to seepage and effective stress; Also acquire ability to estimate seepage losses across hydraulic structure
- Will be able to estimate shear strength parameters of different types of soils using the data of different shear tests and comprehend Mohr-Coulomb failure theory.
- Ability to solve practical problems related to estimation of consolidation settlement of soil deposits also time required for the same.
