"Notch" in Retaining Wall Heel
"Notch" in Retaining Wall Heel
(OP)
We've designed a conventional cast-in-place cantilever retaining wall, and we need to "notch" our heel to accommodate precast drainage basins. (See attached)
I'm befuddled with how to analyze the wall and calculate a maximum toe pressure.

f = P/A +My/I
where y is the distance from centroid to the toe.

So perhaps the 36" of footing/stem on either side takes the additional 3 feet (half of the 6 ft notch) of lateral earth pressure.

There are not calculations or code clauses for everything.

I think three feet either side will be a good way to do it, thanks everyone.

Michael.
Timing has a lot to do with the outcome of a rain dance.

Now, your walls ability to resist the load at the notch, and the subsequent load transfer in your wall, is what I am sure you are referring to.
