As per the Rankine's earth pressure theory, which of the following statements is/are FALSE?

The figure shows a vertical retaining wall with backfill consisting of cohesive-frictional soil and a failure plane developed due to passive earth pressure. The forces acting on the failure wedge are: P as the reaction f...

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 statement is correct for which one of the fo...

A vertical retaining wall of 5 m height has to support soil having unit weight of 18 kN/m³, effective cohesion of 12 kN/m², and effective friction angle of 30°. As per Rankine's earth pressure theory and assuming that a...

A retaining wall of height H with smooth vertical backface supports a backfill inclined at an angle β with the horizontal. The backfill consists of cohesionless soil having angle of internal friction φ. If the active lat...

Consider a rigid retaining wall with partially submerged cohesionless backfill with a surcharge. Which one of the following diagrams closely represents the Rankine's active earth pressure distribution against this wall?

A 3 m high vertical earth retaining wall retains a dry granular backfill with angle of internal friction of 30° and unit weight of 20 kN/m³. If the wall is prevented from yielding (no movement), the total horizontal thru...

A rigid smooth retaining wall of height 7 m with vertical backface retains saturated clay as backfill. The saturated unit weight and undrained cohesion of the backfill are 17.2 kN/m³ and 20 kPa, respectively. The differe...
