Active Earth Pressure

Passive Earth Pressure

|
The pressure exerted by backfill soil on retaining wall, is called as active earth pressure.
|
The pressure exerted by retaining wall on soil is known as passive earth pressure.
|
|
It is developed due to movement of wall away from backfill.
|
It is developed due to movement of wall towards backfill.
|
|
Active earth pressure should be less for stability of retaining structures.
|
Passive earth pressure should be more to ensure stability of retaining structures.

Answer :
Active earth pressure: The minimum earth pressure on retaining wall which is developed due to movement of wall away from backfill is called as active earth pressure.
Passive earth pressure: The maximum earth pressure on retaining wall which is developed due to movement of wall towards backfill is called as passive earth pressure.
Answer :
Active earth pressure and passive earth pressure are two types of soil pressures that occur on retaining walls and other structures that are built into or on top of soil.
Active earth pressure is the pressure exerted on a retaining wall by soil that is pushing against it from behind. It occurs when soil is retained at an angle greater than the angle of repose, which is the angle at which soil naturally settles. Active earth pressure is caused by the weight of the soil pushing against the wall and is affected by the density, angle of repose, and the height of the soil behind the wall. The pressure is maximum at the base of the wall and decreases as the height increases.
Passive earth pressure, on the other hand, is the pressure exerted on a retaining wall by soil that is being compressed from in front of the wall. It occurs when soil is retained at an angle less than the angle of repose and is caused by the weight of the soil and the force of gravity. Passive earth pressure is less than active earth pressure and increases as the height of the soil increases.
In summary, active earth pressure is the soil pressure that acts on the wall when the soil is behind the wall and passive earth pressure is the soil pressure that acts on the wall when the soil is in front of the wall.
