- To help the student discover the soil’s index properties and to classify them.
- To introduce the idea of Seepage of water into soils and determine Seepage’s discharge.
- To help students discern between consolidation and compaction of soils and to assess the extent and rate of settlement due to consolidation.
- The student will be able to comprehend the notion of the shear strength of soils, assessment of shear properties of sands and clays, as well as the fields of their use.
Introduction The formation of soil – clay mineralogy and soil structure Adsorbed water volume Relationship – Relative Density.
Index properties of soils Grain size analysis Methods for Hydrometer and Sieve consistent indexes and limits – Different types of soil classifications – Unified soil classification and I.S. Soil classification.
Permeability Soil water capillary rise – one dimensioned flow of water in soils – Darcy’s LawPermeability – Factors that affect the determination by the laboratory of the coefficient of permeability. Of layers of systems.
Geostatic Stresses Absolute and neutral stress quick conditions for sand

- The student should be aware of the definitions of the various soil mechanics parameters and determine their inter-relationships.
- The student needs to understand the techniques for determining the various soil index properties and be able to classify the soils.
- The student needs to understand the importance of soil’s various engineering properties, like compaction, permeability, and shear strength. They should be able to determine their importance in the lab.
- The student must be competent to apply these principles in daily civil engineering practices.
