CPT interpretations <br /> The parameters selected for output from the program are often specific to a particular project. As such, <br /> not all of the interpreted parameters listed in Table 1 may be included in the output flies delivered with this <br /> report. <br /> Table 1 <br /> CPT Interpretation Methods <br /> Interpreted Description Equation Ref <br /> Parameter <br /> Mid Layer Depth <br /> DepthDepth(Layer Top)+Depth(Layer Bottom)/ <br /> (where interpretations are done at each point then Mid 2.0 <br /> Layer Depth=Recorded Depth) <br /> Elevation Elevation of Mid Layer based on sounding collar elevation Elevation=Collar Elevation-Depth <br /> supplied by client <br /> i <br /> AvAvggc=—�,4,gqc Averaged recorded tip value(q�) <br /> n=1 when interpretations are done at each point <br /> Averaged corrected tip(qi where: 4, <br /> Av qt n"'g 9,j`�•{�l_"�"` n=1 when interpretations are done at each point <br /> Avers=1�fs <br /> Avgfs Averaged sleeve friction(f.) ° <br /> n=1 when interpretations are done at each point <br /> Averaged frictlon ratio(Rf)where friction ratio is deflned Avgfs <br /> AvgRfs4 <br /> �tj=loo°i fs n=1 when interpretations are done at each point <br /> qt <br /> Avgu= L�U, <br /> Avgu Averaged dynamic pore pressure(u) n -� <br /> n=1 when interpretations are done at each point <br /> Averaged Resistivity(this data is not always available wgu= RESISTIVITY, <br /> Avg Res since it is a specialized'test requiring an additional n f-, <br /> module) n=1 when interpretations are done at each point <br /> Averaged UVIF ultra-violet induced fluorescence (thisAvg-= EUVIF, <br /> Avg UVIF data is not always available since it is a specialized test n,., <br /> requiring an additional module) n=1 when interpretations are done at each point <br /> 1 <br /> AvgTemp Averaged Temperature(this data is not always available � Avgar=nETEMPERATURE, <br /> since it is a specialized test) n=1 when interpretations are done at each point <br /> Averaged Gamma Counts(this data is not always Avgu�'EGAMMAf <br /> AvgGamma available since it is a specialized test requiring an n,-, <br /> additional module) n=1 when interpretations are done at each point <br /> Soil Behavior Type as defined by Robertson and I <br /> SBT I See Figure 1 1 2, 5 <br /> Campanella ! <br /> Unit Weight of soil determined from one of the following <br /> user selectable options: <br /> U Wt See references 5 <br /> 1) uniform valve <br /> 2) value assigned to each SST zone <br /> 3) user supplied unit weight profile <br /> Total vertical overburden stress at Mid Layer Depth.
