11 sections • 35 lectures • 3h 10m total length

Introduction3:17
Explore the purpose and function of retaining walls, define soil factors and the internal friction angle, compare concrete retaining walls, and master earth pressure calculations and design checks.
What Is A Retaining Wall6:23
Internal Friction Angle Φ5:56

Vertical & Horizontal Forces Types4:32
Analyze vertical and horizontal forces on retaining walls, including wall weight, base weight, backfill and water pressures, and active and passive earth pressures.
Active Earth Pressure9:37
Active earth pressure is soil movement pushing the wall away, driven by a sliding wedge and shear resistance. Lateral pressure equals vertical stress times a coefficient, contrasted with passive pressure.
Passive Earth Pressure3:29
Explain passive earth pressure by showing soil moves into the wall, opposite the active case, and how vertical principal stress multiplied by a passive coefficient yields the passive pressure.
At Rest Earth Pressure6:31

Rankine Theory (Active Earth Pressure)6:52
The General Case for Rankine Active Earth Pressure5:27
Why Not Using Clay Backfilling4:42
Rankine Theory (Passive Earth Pressure)3:48
The General Case For Rankine Passive Earth Pressure2:48
Explore Rankine active and passive earth pressures, including alpha inclination and the Indrani and Ganjgal 1997 relation, with the note that backfill is usually horizontal.

You will learn the behavior of concrete retaining walls and how it resists different type of loads such as lateral earth pressure, water pressure, surcharge loads and earthquakes loads.
We will start by illustrating all the different types of retaining walls such as Gravity walls, Gabion walls, Cantilever walls and Counterfort walls and when to use each of them.
Then we will go through a detailed illustration for all the three types of earth pressures (Active, Passive and at Rest) and the different calculation methods (Rankine and Coulomb’s) and when to use each of them, then we will go through the walls design checks regarding sliding, overturning and bearing capacity.
All theories and concepts will be illustratred using very neat sketches and graphics prepared specially for this course to make it crystal clear for you during your learning.
All the above will be illustrated by many solved examples for better understating of the theories and how to apply it properly, the last chapter will deal with the seismic behavior of retaining walls during earthquakes and how to calculate the additional seismic forces acting on the walls.
After this course you will be able to analyze and design any type of Retaining walls and use earth pressure theories properly in the design process.
