At which structure (place) retaining wall resist passive earth pressure?
Jishnu Raj
Passive earth pressure conditions are
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.
