EN8491 WATER SUPPLY ENGINEERING NOTES 2017 REGULATION
In this post we have posted some notes on CE8591 FOUNDATION ENGINEERING of PROFESSIONAL CORE for ANNA UNIVERSITY AFFILIATED COLLEGES STUDENTS.
Here We have listed the the notes whichever we could collect for CE8591 FOUNDATION ENGINEERING subject, We think that it will be helpful for your exam preparation.
👉 To impart knowledge to plan and execute a detail site investigation programme, to select geotechnical design parameters and type of foundations. Also to familiarize the students for the geotechnical design of different type of foundations and retaining walls.
UNIT I SITE INVESTIGATION AND SELECTION OF FOUNDATION
Scope and objectives – Methods of exploration – Auguring and boring – Wash boring and rotary drilling – Depth and spacing of bore holes – Soil samples – Representative and undisturbed – Sampling methods – Split spoon sampler, Thin wall sampler, Stationary piston sampler – Penetration tests (SPT and SCPT) – Data interpretation – Strength parameters – Bore log report and Selection of foundation.
UNIT II SHALLOW FOUNDATION
Location and depth of foundation – Codal provisions – Bearing capacity of shallow foundation on homogeneous deposits – Terzaghi’s formula and BIS formula – Factors affecting bearing capacity – Bearing capacity from in-situ tests (SPT, SCPT and plate load) – Allowable bearing pressure – Seismic considerations in bearing capacity evaluation. Determination of Settlement of foundations on granular and clay deposits – Total and differential settlement – Allowable settlements – Codal provision – Methods of minimizing total and differential settlements.
UNIT III FOOTINGS AND RAFTS
Types of Isolated footing, Combined footing, Mat foundation – Contact pressure and settlement distribution – Proportioning of foundations for conventional rigid behaviour – Minimum thickness for rigid behaviour – Applications – Compensated foundation – Codal provision
UNIT IV PILE FOUNDATION
Types of piles and their functions – Factors influencing the selection of pile – Carrying capacity of single pile in granular and cohesive soil – Static formula – Dynamic formulae (Engineering news and Hileys) – Capacity from insitu tests (SPT and SCPT) – Negative skin friction – Uplift capacity- Group capacity by different methods (Feld’s rule, Converse – Labarra formula and block failure criterion) – Settlement of pile groups – Interpretation of pile load test (routine test only), Under reamed piles – Capacity under compression and uplift – Cohesive – expansive – non expansive – Cohesionless soils – Codal provisions.
UNIT V RETAINING WALLS
Plastic equilibrium in soils – Active and passive states – Rankine’s theory – Cohesionless and cohesive soil – Coulomb’s wedge theory – Condition for critical failure plane – Earth pressure on retaining walls of simple configurations – Culmann’s Graphical method – Pressure on the wall due to line load – Stability analysis of retaining walls – Codal provisions.
TOTAL: 45 PERIODS
Students will be able to
👉 Understand the site investigation, methods and sampling.
👉 Get knowledge on bearing capacity and testing methods.
👉 Design shallow footings.
👉 Determine the load carrying capacity, settlement of pile foundation.
👉 Determine the earth pressure on retaining walls and analysis for stability.
