Regression Coefficients

The specific skin friction depends on regression coefficients a, b. The pile base resistance (at the full mobilization of skin friction) depends on the regression coefficients e, f. The values of these regression coefficients were derived from equations of regression curves constructed based on statistical analysis of the results of approximately 350 static loading tests of piles.

The dialog window for entering regression coefficients can be displayed in the frame "Settlement" using the "Edit a, b", "Edit e, f" buttons. When editing the dialog window displays the recommended values of regression coefficients for various types of soils and rocks.

Dialog window "Input for load settlement curve" - input of regression coefficients a, b (e, f)
