**bobpursley**, Saturday, April 16, 2011 at 7:08pmThe horizontal pressure on the wall is densitywater*g*depth/2

The force of friction on wall is

mu*densityconcrete*depth*.87*100*g

setting these two equal

pressure*area=frictionforce

densitywater*g*depth/2*depth*100=mu*denstiyconcrete*g*depeth*.87*100

depth=2*.87*mu*densityconcrete/densitywater. check my math.
