Retaining wall holding 16-17 feet of soil
Retaining wall holding 16-17 feet of soil
(OP)
I'm designing a retaining wall to hold about 17 feet of soil. For a traditional cantilevered wall design, I am getting a stem thickness of about 18 inches, which seems very large.
Should I start considering a counterfort wall or some other option that may be more economical?

Is tapering the wall generally worth it?

Also, I'm going to have to run a drain pipe along the wall that will drain around the building, which is 200' feet long. Any ideas on how to calculate the required slope and size of the drain pipe?

Little confused by your statement 'not practical'. Stability and bending deflection are surely controllable through design.

The wall will be built and backfilled before the building is erected.

You didn't mention slope of ground up hill. Any slope there increases the pressure by either pressure criterion.
Most drains are laid level and set low enough in elevation to allow some higher position for the hydraulic head mid-length. Size generally is "what ever is common" in the area, because most of these drains never run full unless you are tapping a spring in gravel. 4" diam. in the states is common. See some threads elsewhere dealing with "French Drains". Be aware of possible plugging if only gravel is the backfill (not a filter).
