- This tool is for evaluating the soil by pressuremeter test, as shown in the figure above.
- All the input parameters should be positive.
- The volume of the measuring cell is default as 0.000535 m
^{3}. - Zone 1, 2 and 3 represents the reloading portion, the pseudoelastic zone and plastic zone respectively.
- The state between zone 1 and 2 is "initial point". The state between zone 2 and 3 is "creep point". The state at the end of zone 3 is "limit point".
- p
_{l}and N_{p}are only used to obtain the preconsolidation pressure σ′_{c}and the undrained shear strength c_{u}in clay. - For "nan", "0" or "inf" displayed in Results, please check your input parameters.
