Do I need to count the active pressure on key of retaining wall?
Do I need to count the active pressure on key of retaining wall?
(OP)
When I working on a retaining wall, a key seems necessary for resisting sliding. I am wondering do I need to count the soil pressure on key? I use a software called retainingpro, it doesn't include that force.

I was arguing with an engineer in my office onetime that it should not be including because I believe soil below the level of the retaining wall footing will be in an in-situ state and that the active earth pressures will not be developed. I did not win that argument and now go with the more conservative assumption that active earth pressure does act on the key.

the key is below the pivot point of the wall structure and any active pressure acting on it should counter the overturning moment... however this benefit is ignored unless you're designing sheet piles.
