Max. Equivalent Fluid Density
Max. Equivalent Fluid Density
(OP)
I am looking for the maximum equivalent fluid density of soil used in the design of poured concrete retaining walls (see Reward Wall Systems). The borings encountered SC overlying CL with N-values from 7 to 19. Is there any similarity between the equivalent fluid density and equivalent fluid pressure? Thanks for your input.

I printed this thread out back when it was new. I am about to send some info to a mining engineer in Canada about max pressures. In that thread, which he started, some engineers expressed the opinion that pressures never even get up to full hydrostatic. I disagree and so does at least one of my reference books. I plan to fax a copy of this thread to him too but I was wondering ,were those 80 to 90 pcf equivalents you mentioned measured or calculated. I have calculated equivalent hydrostatics as high as 81 pcf. I am looking for as much info to back up the higher pressures as possible, especially if it was gained by some kind of actual field testing. Also I am interested in finding out what kind of tests could be conducted say near the face of a retaining wall or bulkhead.
Thanks,
