Course Objectives:

• To calculate earth pressure under different loads and conditions
• To check the stability of gravity and cantilever Retaining walls
• To design sheet pile walls and bracings
• To design Reinforced soil walls

Course Outcomes

At the end of the course, student will be able to

• Calculate the earth pressures under different loads and conditions
• Design conventional retaining walls and check the stability
• Design flexible retaining walls, like sheet piles and reinforced earth walls
• Design the supporting systems for deep excavations

UNIT - I

Earth Pressure Theories: Rankine’s and Coulomb’s Earth pressure theories for cohesive and cohesionless soils, stresses due to compaction and surcharge loads.

UNIT - II

Conventional Retaining Wall: Types of retaining walls, Stability (sliding, overturning, bearing capacity & overall) of gravity and cantilever walls, proportioning of retaining walls, Backfill material and drainage.

UNIT - III

Flexible Walls: Sheet pile walls, Construction methods- Cantilever and Anchored (Free and Fixed support methods) sheet pile walls in coarse- and fine-grained soils, moment reduction method.

UNIT - IV

Reinforced Soil Walls/Mechanically Stabilized Earth: - Failure mechanisms-bond and rupture failures, Analysis methods, Limit equilibrium method- Internal and external stability, Static analyses.

UNIT - V

Braced Cuts and Soil Nailing: Lateral earth pressure in braced cuts, Design of various components, Stability of braced cuts, base heave and stability, yielding and settlement of ground surrounding excavation, Soil Nailing.
