(OP)
Im just to design a propped retaining wall. My superior wants one face reinforcements but I think that is not propper as propped retaining wall experience both positive and negative moment. I preffer putting reinforcements at both faces, near and far face. Please advice!

DaveAtirks the wall is cantilever and lateral supported at top. The height of which is about 2.5m high. It retains a lot of backfill soil.

Im asking why should I just reinforce one face while the nature of the bending moment shows there is positive and negative moments along the wall and there is also a point of zero moment. The bending moment needs 2 face reinforcements.

I do not understand the existance of any negative moment here if it is truly a basement wall - all that type of wall sees is positive moment with the steel on the side away from the soil. The only circumstance that would produce any negative moment on a "basement wall" here is if the wall retained enough earth above the level of support of the wall diaphragm, or prop level, as you put it, to generate a negative moment.
So...Does the earth extend above the "prop"?
Also, if the wall is 10" thick or greater, I would install two mats of steel anyway, using minimum steel requirements and distribution per ACI where appropriate.
