Earth Pressure

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 respect to the major principal plane for Ranki...

Consider the statements P and Q related to the analysis/design of retaining walls. P : When a rough retaining wall moves toward the backfill, the wall friction force/resistance mobilizes in upward direction along the wal...

A vertical trench is excavated in a clayey soil deposit having a surcharge load of 30 kPa. A fluid of unit weight 12 kN/m 3 is poured in the trench to prevent collapse as the excavation proceeds. Assume that the fluid is...

As per Rankine's theory of earth pressure, the inclination of failure planes is $$\left( {45 + {\phi \over 2}} \right)^\circ $$ with respect to the direction of the minor principal stress. The above statement is correct...

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 a soil element to reach the failure stat...
