passive state

A vertical smooth rigid retaining wall is supporting horizontal ground with dry cohesionless backfill having a friction angle of 30°. The inclinations of failure planes with respec...

As per Rankine's theory of earth pressure, the inclination of failure planes is $(45 + \frac{\phi}{2})°$ with respect to the direction of the minor principal stress. The above stat...

Let $$\sigma$$' v and $$\sigma$$' h denote the effective vertical stress and effective horizontal stress, respectively. Which one of the following conditions must be satisfied for...
