Stability of retaining walls against overturning

Article Abstract:

A study on the stability of retaining walls against overturning is evaluated. The study found that retaining walls should be analyzed using the position of the resultant force on the base since this is not affected by the arbitrarily assumed surface. The assumed thrust surface also has no impact on the safety factors against sliding and bearing capacity. However, it is argued that two equations presented in the study can be used to compute for the factor of safety against sliding. It is also shown that the factor of safety against bearing capacity is affected by the resultant force location.
