CPT Interpretations Li The parameters selected for output from the program are often specific to a particular project. As such, not all of the interpreted parameters listed in Table 1 may be included in the output files delivered with this + report. Table 1 CPT interpretation Methods Interpreted Description Equation Ref Parameter Mid Layer Depth Depth (where interpretations are done at each point then Mid Depth(Layer Top)+Depth(Layer Bottom)/2.0 Layer Depth=Recorded Depth) Elevation Elevation of Mid Layer based on sounding collar elevation Elevation=Collar Elevation-Depth supplied by client Avggc Averaged recorded tip value(qc) Avggc n=1 when interpretations are done at each point Averaged corrected tip(q,}where: Avggt= �q, Avgqt n n=1 when interpretations are done at each point Avgfs=1 i fs Avgfs Averaged sleeve friction(fs) n n=1 when interpretations are done at each point Averaged friction ratio(Rf)where friction ratio is defined Avgs f as: AvgRf=100%• AvgRf .4 Avggt Rf=100%•qr n=1 when interpretations are done at each point 1 Avgu Averaged dynamic pore pressure(u) Avgu n-1 n=1 when interpretations are done at each point Averaged Resistivity(this data is not always available 1 AvgRes since it is a specialized test requiring an additional Avg"=nRESISTIYITY; module) n=1 when interpretations are done at each point Averaged WIF ultra-violet induced fluorescence (this _ 1 AvgUVIF data is not always available since it is a specialized test Avgu n-I requiring requiring an additional module) n=1 when interpretations are done at each point AvgTemp Averaged Temperature(this data is not always available Avgu=n±TEMPERATURE, since it is a specialized test) n=1 when interpretations are done at each point Averaged Gamma Counts(this data is not always Avgu_'±GAMMA, AvgGamma available since it is a specialized test requiring an n to additional module) n=1 when interpretations are done at each point SBT Soil Behavior Type as defined by Robertson and See Figure 1 2,5 Campanella Unit Weight of soil determined from one of the fallowing user selectable options: U.Wt.
