At which structure (place) retaining wall resist passive earth pressure?
AdityaBhandakkar
The moment of the wall towards the backfill, in this case, the lateral earth pressure called a passive earth pressure.
In the case of passive earth pressure,
Major principal stress = lateral pressure
Minor principal stress = vertical pressure
In this case, soil exerts a pull on a retaining wall where the inner rupture plane called as a failure plane makes at (45- fi/2) angle with horizontal.
At depth=0 , Rankines passive force= 0
If q is a surcharge load acting on backfill, then lateral pressure = K.q applied throughout the depth of retaining wall.
