Does anyone have any decent summarised capacity tables for a standard steel post, concrete sleeper cantilever retaining wall.
I am comparing some the results I am getting using a design module on the clearcalcs software to some older (2018) span tables and for a retaining wall with specs 2m spaced 100UC14.8 verticals, 1.6m retaining height, flat retained soil (friction angle 28, unit weight 19),5kpa surcharge, 450mm diam piers, into natural clay foundation soil (Su 25kpa) I am getting the pier embedment depth needs to be 3.5m in clearcalcs whereas the span tables only require the pier embedment depth to be 1.9m. The clearcalcs software uses BROMS method if that helps. I am just wondering why such a big difference between the two? Any comments welcomed.
