I have a project for combined sewer outflows to design a concrete drop shaft.  The idea is to construct a concrete slurry diaphragm wall below grade subject to external water and soil pressures.  The wall will be subject to ring compression.  What section of ACI is used for strength design per owner requirements.  Is it section 10 or 14 for walls to determine nominal compressive capacity?  The shaft is 60 feet in diameter and about 60 feet deep.

I would use Chapter 10, but if the owner has requirements use those so long as they are not less than the code.

Remember, while the water load may be symmetrical the soil load will almost certainly not be resulting in bending, not just uniform compression in the ring.  Also, I imagine the ring will be cast in segments, you will need to account for the lack of continuity across these segments (ring of ball bearing type of problem)
