Retaining wall in slopes
Retaining wall in slopes
(OP)
Hi, perhaps this is a basic question but, why the failure plane of the slope always pass thru the wall heel for slope stability analysis in cantilever concrete retaining walls? I was thinking on that but cold not find a good answer. If this is for fill areas, I can see that perhaps the failure plane "follows" the plane between the existing and fill soils behind the retaining wall and therefore the failure plane touches the wall heel. But I am not sure if this is correct...

There may be some configurations like Mike mentions above where the failure plane goes further below a concrete wall but that requires less than uniform soil conditions and almost a special case situation. Generally, if the failure plane does not go right around the heel, I think the modeling is suspect and that the search limits need to be reviewed.
