For a sandy soil having an angle of internal friction 30°, the ratio of passive and active lateral earth pressure will be
A 6 m high retaining wall having a smooth vertical back face retains a layered horizontal backfill. Top 3 m thick layer of the backfill is sand having an angle of internal friction, ϕ = 30° while the bottom layer is 3 m thick clay with cohesion, C = 20 kPa. Assume unit weight for both sand and clay as 18 kN/m3. The total active earth pressure per unit length of the wall (in kN/m) is:
A retaining wall with vertical back retains a mass of cohesion-less soil, surface of which is level with top of the wall. Active lateral earth pressure coefficient (in terms of 'ϕ') i.e. angle of internal friction of backfill is given by:
A 6 m high retaining wall with a vertical back has a backfill of silty sand with a slope of 10° for the backfill. With values of KH = 760 kg/m2/m and KV = 100 kg/m2/m, the total active earth pressure will approximately be
A retaining wall retains a sand strata with ϕ = 30° up to its top. If a uniform surcharge of 12 t/m2 is subsequently put one the sand strata, then the increase in the lateral earth pressure intensity on the retaining wall will be
A homogeneous gravity retaining wall supporting a cohesionless backfill is shown in the figure. The lateral active earth pressure at the bottom of the wall is 40 kPa. The minimum weight of the wall (expressed in kN per m length) required to prevent it fromoverturning about its toe (Point P) is
In the design of the retaining wall, both, active earth pressure and passive earth pressure are considered due to soil available on both sides (with different heights) of the R. C. C retaining wall. If the angle of repose, ϕ = 30°, then what will be the relation between the coefficient of active earth pressure (Ka ) and passive earth pressure (Kp )
An earth-retaining structure may be subjected to the following lateral earth pressures:1. Earth pressure at rest;2. Passive earth pressure;3. Active earth pressure.The correct sequence of the increasing order of magnitudes of these pressures is
How much increase in pressure will be, if a uniform surcharge of 120 kN/m2 is placed on the back fill with Φ = 30°
If the lateral pressure on a retaining wall is high, the following measure are taken while designing:

A retaining wall 10 m high with a vertical back retains moist sand with a horizontal surface. If unit weight of sand is 15 KN/cum and the angle of internal friction is 30 degree, the total active pressure (in KN) experienced by the wall per m run is
