The M.D. Fredlund dialog contains parameters needed to fit the compression curve with the M. D. Fredlund (2000) equation. To allow the compression curve to be used as the basis for volume change calculations, the experimental data must be best-fit with an equation. A modified Fredlund and Xing (1994) equation along with a fitting algorithm was used to best-fit the experimental compression data. The M. D. Fredlund equation provides a reasonable method of describing the compression curve. A description of the theory can be found in the SVSOILS Theory Manual.

 

aco: The aco field refers to a fitting parameter in the M.D. Fredlund (2000) equation.

 

nco: The nco field refers to another fitting parameter in the M.D. Fredlund (2000) equation.

 

mco: The mco field refers to another fitting parameter in the M.D. Fredlund (2000) equation.

 

hrco: The hrco field refers to a fixed fitting parameter relating to lower part of curve.

 

Fit: The Fit field indicates whether the fit algorithm has been successfully executed on the current data.

 

Error: The Error is the difference between the fitted results and the laboratory values in terms of R2.
