Oedometer Constrained Modulus (Eoed) from Coefficient of Volume Compressibility (mv)
Oedometer constrained modulus is obtained from the standard one-dimensional compressibility relationship used in classical settlement interpretation.
Soil Profile Plot
Build a compressibility profile by borehole and sample depth. Use mv directly when oedometer data are available, or estimate Eoed from the PI-f2 chart and N60 as a screening alternative.
mv should be taken at the oedometer stress level corresponding to the relevant sample stress.
PI is auto-filled from selected borehole samples when available. N60 is auto-filled from saved project parameters when an SPT correction result exists at the same depth.

Save Profile Analysis
Save current profile inputs and plot images to the active project folder.
Cloud save is available from Bronze upward. Register for an account to use cloud save. You can still use tools with manual inputs.
Select a project/borehole from the top-right dropdown first.
