Tiered Drilled Shaft Retaining Wall
Tiered Drilled Shaft Retaining Wall
(OP)
I am in need of some clarity. I have a retaining wall system that is composed of two cantilever drilled shaft walls, one behind the other, and my question is whether the top wall has any influence on the lower wall?

The top wall is 14' high, the bottom wall is 22' high and there is a 20' horizontal setback. Is there any surcharge from the higher wall acting on the lower wall and if so, how is something like that computed?

Your picture of the lower wall shows no embedment.

By the way, the 1/2 the wall height is a rule of thumb for "simple" configurations that even then doesn't always work. What you have is far from simiple.

If you want to analize the problem, look up earth pressures in a good graduate level soils mechanics book and get to work.

Now you may also say that the drilled shafts have some center to center spacing, you may tell me about Cp values as determined from triaxial strength testing. It would not change my earlier statement. There is some free-body diagram that needs to be addressed and the problem is ONE problem.
Just my thoughts. . .
