| Utility Formulas | Description | Symbol Definitions |
| i=k*zO | width of settlement trough | i=width of settlement trough(mm) |
| Smax=S/e^(-x^2/2*i^2) | predicted maximum settlement from settlement reading | zO=depth(mm) |
| S=Smax/e^(-x^2/2*i^2) | settlement at x distance from know Smax | k=coefficient |
| s=-2.5*i*Smax | settlement volume area | s=settlement(mm) |
| VL=s/(π/4*d^2) | volume loss using volume area | Smax=predicted maxsettlement(mm) |
| Smax=-(0.00313*VL*d^2)/i | Smax from value loss | s=settlement volume area(mm^2) |
| v=π/4*d^2*VL | volume of settlement trough (v) using volume liss | VL=volume loss |
| v=S*ν（2*π*i^2）/e^(-y^2/2i^2)*(g(xi)-g(xf)) | volume of settlement trough using know settlement using reversed function to predict settlement in 3D | d=diameter(mm) |
| S=v*e^(-y^2/2i^2)*(g(xi)-g(xf))/ν(2*π*i^2) | settlement at certain point using know volume | g(x)=gaussian function applied to x |
