The latter is of course more realistic; only the effective stresses determine plasticity, not the water pressures. OF<n T

In other words, using total stress analysis is only correct when the calculation is elastic. But this case is not very often in reality. U.Chf9a -

Suggestion: Try to use effective stress analysis when it is undrained condition (typically, there is option for this in PLAXIS)." A
