CPT Interpretations <br /> The parameters selected for output from the program are often specific to a particular project. As such, <br /> l not all of the interpreted parameters listed in Table 1 may be included in the output files delivered with this <br /> report. <br /> Table 1 <br /> CPT Interpretation Methods <br /> Interpreted Description Equation Ref <br /> Parameter <br /> Mid Layer Depth <br /> Depth (where interpretations are done at each point then Mid Depth(Layer Top)+Depth(Layer Bottom)/2 p <br /> Layer Depth=Recorded Depth) <br /> Elevation Elevation of Mid Layer based on sounding collar elevation Elevation W Collar Elevation-Depth <br /> supplied by client <br /> Av c Averaged recorded ti value Avggc 1 .1 <br /> 9q 9 P (q�) n,-� <br /> n=1 when interpretations are done at each point <br /> Averaged corrected tip(Q where: Avggt='L4, <br /> Avggt q,=qe+(I-a)•u n`"' <br /> n=1 when interpretations are done at each point <br /> Avgfs Averaged sleeve friction(f.) - As-t ifs <br /> n=1 when interpretations are done at each point <br /> Averaged friction ratio(Rf)where friction ratio is defined AvOs <br /> Av Rf as: AvgRf=loo%*Avgqt <br /> 9 Rf=100%•At <br /> n=1 when interpretations are done at each point <br /> I <br /> Avgu Averaged dynamic pore pressure(u) Avgu.=n Eu; <br /> n=1 when interpretations are done at each point <br /> Averaged Resistivity(this data is not always available 1 <br /> Avg" <br /> AvgRes since it is a specialized test requiring an additional n ERESISTIVITY; <br /> module) n=1 when interpretations are done at each point <br /> Averaged tall=ultra-violet induced fluorescence (this I <br /> AvgUVIF data is not always available since it is a specialized test - UHF, <br /> n <br /> requiring an additional module) n=1 when interpretations are done at each point <br /> Av Tem Averaged Temperature(this data is not always available Avgu= 't t TEMPERATURE, <br /> AvgTemp since it is a specialized test) <br /> n=1 when interpretations are done at each point <br /> Averaged Gamma Counts(this data is not always I <br /> A'g" <br /> AvgGamma available since it is a specialized test requiring an - GAMMA, <br /> additional module) n=1 when interpretations are done at each point <br /> SBT Soil Behavior Type as defined by Robertson and See Figure 1 I 2,5 <br /> Campanella <br /> Unit Weight of soil determined from one of the following <br /> user selectable options: <br /> U.Wt. 1) uniform value See references 5 <br /> 2) value assigned to each SBT zone <br /> 3) user supplied unit weight profile <br /> Total vertical overburden stress at Mid Layer Depth.
