Geotechnical Tools
A structured collection of calculation tools covering key areas of geotechnical engineering, from site characterisation to analytical methods.
Rigidity / Deformation Tools
Undrained Deformation Modulus (Eu) from Standard Penetration Test (N60)
Uses the Butler (1975) correlation for cohesive soils, where Eu/N60 is taken within 1000 to 1200 kN/m2 for preliminary screening.
Soil Profile Plot
Enter corrected SPT resistance by sample depth. For cohesive soils, this profile uses Butler (1975) with Eu/N60 within 1000 to 1200 kN/m2, then computes Eu from Eu = (Eu/N60)N60.
