Footing Anchored On Inclined Rock Surface
Footing Anchored On Inclined Rock Surface
(OP)
I am designing a 15 foot high concrete retaining wall that is 150 feet long on a steep 15% grade. The base for the footing is very hard and smooth diabase bedrock which will need anchoring of the the footing to it. Any suggestions on the design process for the footing and the dowels into the rock for shear resistance only will be appreciated.

The keys would then be analyzed as concrete shear keys.

Thanks for the quick response. The shear key you are describing runs along the wall for 150ft. My key/dowels into the rock is actually perpendicular to the wall to resist the sliding forces from the steep 15% grade condition.

No sheet piling at all. This is a convential L shape 15 foot high cantivered retaining wall with a large toe anchored with high strength Willaims Form Eng'g 75ksi grouted dowels to the inclined rock surface. The design is still at issue with the Geotech.

I like your analysis and comparison to an anchor bolt. I am wondering if there is any type of publication/research on your XS pipe anchor design concept?? Thanks.
