Pile Foundation Tool (clay)

Tips

• This tool is for calculating pile foundation bearing capacity in clay, as shown in the figure above.
• The friction resistance is calculated by α method, λ method and β method.
• The point bearing resistance iscalculated by Meyerhof's method and Vesic's method.
• The ultimate pile load is calculated by the averaged values from different methods.
• Drained friction angle of remolded clay φ′_R is only used by β method for friction resistance.
• All the input parameters should be positive.
• The unit weight of water is 9.8 kN/m³, and the atmospheric pressure is 100 kPa.
• For "nan", "0" or "inf" displayed in Results, please check your input parameters.
• If Qall is given to estimate Fs, users can try to input different Fs to see the "Qall" in Results. The real Fs corresponds to the caluclated "Qall" same as the given Qall.
• Same logic of trial-error process can be used to estimate the dimension of the pile (diameter & length) for a given Qall and a required Fs.
