If drains get plugged then water may also build up behind the wall? So taking account of some pressure makes a lot of sense in my view. Hmmm, in the worst case this could be as much as 4m=40 kN/m^2 ??
Don't you put some practical reinforcement for shrinkage etc?
Yes, standing water produces 40 kN/m^2 pressure at the bottom. The high wall
has an area of approx 25 m^2, which gives a horizontal force of 500 kN!
Thats too high. The scenario gets more worse when they fill liquid concrete
in the gap between rock/wall. I will talk with my colleagues about that.
Maybe we must add some horizontal anchor bars in the rock.
And we put reinforcement for shrinking.
