Hi, I have some discussion with my colleague about the unit of soil data conversion and we cannot make an agreement especially for T-Z data. Could you help to check is our unit conversion below correct?Says my pile diameter is 36" or 91.44cm or 0.9144m.1. P-Y data: Soil report P = kN/m, Y = mmSACS PSI P = kN/cm, Y = cmThus, P factor 1/100 = 0.01, Y factor = 1/10 = 0.12. Q-Z data: (assuming plugged area)Soil report Q = kN, Z = mmSACS PSI Q = kN/cm^2, Z = cm
Thus Q factor = 1/(PI()*(D/2)^2) = 1/(PI()*(91.44/2)^2) = 1.52e-4, Z factor = 1/10 = 0.13. T-Z data:Soil report T = kN/m, Z = mm
SACS PSI T = kN/cm^2, Z = cmThere are 2 argument here for T factor, one is divided by diameter and the other one is perimeter1. Divided by Diameter, T factor = 1/ (D*100^2) = 1 / (0.9144*100^2) = 1.094e-42. Divided by Perimeter, T factor = 1 / (PI()*D*100^2) =1 / (PI()*0.9144*100^2) = 3.481E-5Factor for Z = 1/10 = 0.1Could you please help to check that our consideration are correct or P-Y and Q-Z, and also which consideration are correct for T-Z?Thanks,Pei Shing
