I am trying to use the Kajima Technical Research Institute, KTRI (Takesue, et al. 1998) method for pile design. In order to calculate the pile side friction you must know the delta u (excess pore water pressure). I believe that a pore water dissipation test can be performed in a clay to find this value, but what about in sands or mixed soil types? I am in Charleston. I have attached a paper that might be helpful.
I already use the LCPC method but would like to compare it to the KTRI method.
