Hi there,
I'm working on a project where there will be a retaining wall on top of a cesspit wall. See below :
I will check the wall stem reinforcement and design it accordingly. However, I am wondering what global checks need to be done (overturning/sliding) as this seems similar to a basement wall configuration.
Sliding for cross-section B-B should be fine as there is an equal force on both sides, so there shouldn't be any unbalanced forces. However, in cross-section A-A, the lateral load from Side X is greater than the other side. In this case, would I only need to check the shear interface between the slab and the wall (for the top wall and slab 8'5" lateral earth/surcharge force) to make sure it can transfer that sliding force to the lower walls and then consider the passive resistance of the lower wall opposite Side X against the full lateral pressure of Side X (15'5") to confirm that the whole system won't slide?
Would overturning be a problem here if the wall is effectively propped approximately mid-height?
