Retaining walls can be divided into two major categories
Conventional retaining walls
Mechanically stabilized retaining walls
stabilized mechanically
Metal strips
Geo-grids
Welded wire mats
Geo-textiles
conventional retaining walls types
Gravity walls
Semi-gravity walls
Cantilever walls
Counter fort walls
design of the conventional retaining walls
Stability check phase: Knowing the lateral earth pressure, the structure is examined for possible overturning, sliding and bearing capacity failure
Strength check phase: Evaluating the amount of reinforcement
Stability check
a. Overturning
b. Sliding
c. Bearing capacity failure
d. By deep seated shear failure
Overturning
Based on the assumption that Rankine active pressure is acting along a vertical plane AB, the Rankine passive force is
factor of safety against overturning about the toe (point C) is given as
factor of safety: 2-3
Calculate The overt turning : read the problem
Check for sliding along the base
The minimum factor of safety against sliding is 1.5
Check for bearing capacity failure
