Thank you for your valuable help and direction. Very useful. I hope I haven't taken too much of your time. The link at engineering.com doesn't seem to work though.... I am not a member of that site, is that the issue? Or maybe the naming of the file is an issue? I couldn't see any requirement...

Foundation is a clay till to some depth sitting on fractured weathered bedrock. Part of the issue that is giving the low F.O.S. for the critical surface through the base is the parameters being used are very conservative. I don't view this as my goal with this review though - as the values are...

No agency or insurance dictating a FOS. I agree the infinite slope is FOS = 1 The issue is that we are getting a FOS < 1.3 for a failure which goes into the foundation. (I've specificed in SlopeW a entry-exit failure which exits in the foundations and enters in the top half of the stockpile on...

When looking at critical failure planes for large/tall stockpiles/surge piles (eg. active dynamic piles), does anyone have a reference for justifying a factors of safety below 1.3 in static analysis. A F.O.S. of 1.3-1.6 is something that would typically be defined as the analysis criteria for a...

23 kN/m3 = 145 pcf Sorry. I use SI units 99% of the time.

100 kPa = 14 psi = 1 tsf 2000 kPa = 290 psi = 21 tsf

I’ve got a general foundation question. I’m trying to figure out how to best list the maxiumum allowable bearing capacity for a single type of soil, but for multiple types and sizes of foundations. In general I can say that the foundations will be on a very dense and consolidated till (phi =...

Howdy, I'm looking at the preliminary design of an MSE Wall for a job. I suppose I'm also interested (or atleast the structural eng will be for wall design) in this question for the adjacent concrete retaining wall that forms the backwall of a large rock crusher. The wall is up to 28 m (92 ft)...
