SF4010 Earth and Rock Fill Dams Syllabus:
SF4010 Earth and Rock Fill Dams Syllabus – Anna University PG Syllabus Regulation 2021
OBJECTIVES:
Students are expected to learn reasons for failure and damages of embankments and slopes, various methods of analysis of slopes and remedial techniques to protect the slopes.
UNIT I DESIGN CONSIDERATION
Design consideration, Factors influencing design, Types of earth and rock fill dams, Design details, Provisions to control pore pressure.
UNIT II SLOPE STABILITY AND SEEPAGE ANALYSIS
Stability of infinite and finite slopes, Method of Slices, Bishop’s method, Flow nets, Stability conditions during construction, Full reservoir and drawdown – cut off walls – Trenches – Importance of drainage and filters.
UNIT III HYDRAULIC FRACTURING
Introduction, Conditions and mechanisms for hydraulic fracturing, Failure criterion for hydraulic fracturing – cubic specimen with a crack – core with a transverse crack – core with a vertical crack, strike–dip of easiest crack spreading; factors affecting hydraulic fracturing, self-healing of a core crack.
UNIT IV FAILURE AND DAMAGES
Failure and damages, Nature and importance of failures in embankment and foundation – Piping, Differential settlement, Foundation slides, Earthquake damage, creep and anisotropic effects, Reservoir wave action, Dispersive piping.
UNIT V SLOPE PROTECTION MEASURES
Special design problems, Slope protection, Filter design, Foundation treatment, Earth dams on pervious soil foundation, Application of Geosynthetic materials in filtration. Treatment of rock foundation, Construction Techniques, Quality control and performance measurement
OUTCOMES:
On completion of the course, the student is expected to be able to
CO1 Assess the causes of failure and damage of embankments and slopes.
CO2 Apply the knowledge of engineering and analyse the stability of slopes for various seepage conditions and apply the concept in the design of earth and rock fill dams.
CO3 Apply the knowledge of engineering and assess the stability of dam against hydraulic fracturing and suggest suitable remedial measure.
CO4 Understand the nature of failures and damages in earth and rock fill dams and apply the concept in field to avoid distress.
CO5 Recommend suitable remedial measures to protect the slopes and implement quality control and monitor its performance
