ROCK DOWELS FOR RETAINING WALLS
ROCK DOWELS FOR RETAINING WALLS
(OP)
I am designing a wall retaining a 1.5:1 back slope. The wall will be more than 9' high above finish grade (acp) and will probably be 11' high total, with the base resting on basalt. To prevent sliding, I was wanting to dowel into the rock with the #6 bars that are also the tension steel for the back of the wall (14" oc). Would this create a case in which the wall would have to be designed for passive pressure as opposed to active, ie would the wall not yield slightly because of the rock dowels?

That's my take on it,

lateral tip deflection/height>0.001 to 0.004 for dense to loose sand backfill to achieve active push status.
Check if you have as much

I strongly recommend that you consult a geotechnical engineering specialist when assessing the loads exerted by the retained material and the stability of the wall.
