About N corrected values
About N corrected values
(OP)
Hi, In the place I am, my boss asked me to correct the SPT N values for dilatancy (dilatancia) and overburden, I am using the peck correction (0.77 log20/p) and the liao Whitman corrections, but when you are about 40 mts you get some values of 0.50 or less.
The question is: Is there any bibliography that gives a recomendation of the minimum Cn value, for example, "use a Minumun Cn value of 0.50"; if so, which is?
We are using a method to calculate skin and tip bearing capacity by means of Wysockey (1999), but I can get the original thesis, some one has it? he is from the Urbana Illinois University.
Thanks

RE: About N corrected values
If you are doing something different from that, be consistent with how the empirical models were developed. I am not familiar Wysockey's work. Your best bet for that is to contact the university, especially if you can identify his or her thesis adviser.
