SF4101	PROPERTIES AND BEHAVIOUR OF SOILS	LTPC

3003

OBJECTIVES:

• To impart knowledge on the various factors governing the Engineering behaviour of soils and the suitability of soils for various Geotechnical Engineering applications.

UNIT I	ORIGIN OF SOILS AND CLAY MINERALS	8

Formation of soils – different soil deposits and their engineering properties – Genesis of clay minerals – classification and identification – Anion and Cation exchange capacity of clays – specific surface area – index properties – bonding in clays.

UNIT II	PHYSICAL AND PHYSIO CHEMICAL BEHAVIOUR OF SOILS	9

Physical and physio chemical behaviour of soils – diffused double layer theory – computation of double layer distance – effect of ion concentration, ionic valency, pH, dielectric constant, temperature on double layer – stern layer – attractive and repulsive forces in clays – types of soil water – mechanism of soil – water interactions - soil fabric and structure.

UNIT III	SWELL - SHRINK AND COMPACTION BEHAVIOUR OF SOILS	10

Swelling and shrinkage behaviour of soils – mechanisms, Causes and consequences – factors influencing swell – shrink characteristics – swell potential ––swell pressure –and measurements – sensitivity, thixotrophy of soils – soil suction – soil compaction – factors affecting soil compaction - case studies.

UNIT IV	COMPRESSIBILITY, SHEAR STRENGTH AND PERMEABILITY BEHAVIOUR OF SOILS	10

Engineering properties - Compressibility, shear strength and permeability behaviour of fine and coarse grained soils – mechanisms and factors influencing engineering properties – basics of soil liquefaction – causes and consequences – case studies.

UNIT V	CONDUCTION PHENOMENA AND PREDICTION OF SOIL BEHAVIOUR	8

Conduction in soils – hydraulic, electrical, chemical and thermal flows in soils – applications - coupled flows – Electro-kinetic process – thermo osmosis - electro osmosis – prediction of engineering behaviour of soils using index properties – empirical equations and their applicability.

TOTAL : 45 PERIODS

OUTCOMES: On completion of the course, the student is expected to be able to

CO1 Classify of soil based on index properties
CO2 understanding of the clay mineralogy and its intricacies and consequences.
CO3 Understand the volume change with response to compaction and seasonal moisture variations.
CO4 interpret the engineering behaviour of soils such as compressibility, permeability and shear strength with index properties so as to design the safe foundation system.
CO5 understand the various geotechnical applications of conduction phenomenon which are of great significance in the case of ground contamination and decontamination, ground improvement methods and land reclamation projects
