Cantilevered retaining walls top deflection
Cantilevered retaining walls top deflection
(OP)
I'm working in the design of some quite high cantilevered retaining walls (height of the stem around 9.50 meters), and I'm worried about the horizontal deflection of its top due to the stem deformation (elastic and due to long term loads). Since the earth pressure varies with the deformation of the stem from the "at rest" coefficient to the fully active one, I guess the correct way of calculating this deflection must be difficult. Since it is a common problem I guess there must be easy formulas available to estimate it. Does someone know where I can find some formulas or charts to calculate this deflection?

Counterfort wall or maybe a reinforced earth system?

If the front face of the wall is vertical, when it deflects, it tends to make the public a little nervous with a wall of that height.

If the wall is in a cut situation, you still may need temporary sheeting and tieback anchors. In effect, you will be building two walls, one temporary and one permanent. In situations like this, a permanent tiedback wall becomes economical. But you would need a permanent easement for the tiebacks.
