Geotechnical & Foundation Engineering

Prerequisites: Soil Mechanics

Specific Objectives of course:

  • To enhance the skills related to baring capacity and settlement evaluation of soils.
  • To apply principles of soil mechanics to engineering problems pertaining to retaining structures, foundations and embankments.
Course Outline:
Earth Pressures: Definition, pressure at rest, active and passive earth pressures. Coulomb’s and Rankine’s theories. Bell’s equation for cohesive frictional soils. Earth pressure diagrams for different loading configurations.
Bearing Capacity of Soils: Definition of: gross, net, ultimate, safe and allowable bearing capacity.  Methods of obtaining bearing capacity:  presumptive values from codes, from plate load test.  Bearing capacity theories.  Bearing capacity from SPT and CPT data.
Settlement Analysis: Definition, total settlement, differential settlement, angular distortion, immediate settlement.  Primary and secondary consolidation settlements. Normally and pre-consolidated soils. Mechanics of consolidation, theory of one dimensional consolidation, assumptions and validity, Oedometer test: determination of compression index and coefficient of consolidation, magnitude and time rate of consolidation settlement. Causes of settlement and methods of controlling settlement. Allowable total and differential settlement.
Slope Stability: Types of slopes, Factors affecting stability and remedies. Types of failure. Methods of analysis: Ordinary methods of slices, Taylor’s stability number method, Swedish circle method.
Earth and Rock Fill Dams: Definition of an earth dam, types of earth and rock fill dams, Components of an earth dam and their functions. General design considerations and typical cross-sections.
Introduction to deep foundations: Types of piles, load carrying capacity of piles, group action, negative skin friction, pile load test.
Soil Improvement: Basic principles, objectives and methods.
Soil Dynamics: sources of dynamic loading, spring-mass-dashpot system, application to machine foundations, liquefaction.
