The latter is of course more realistic; only the effective stresses determine plasticity, not the water pressures. 41XXL$

In other words, using total stress analysis is only correct when the calculation is elastic. But this case is not very often in reality. M <)Vtn

Suggestion: Try to use effective stress analysis when it is undrained condition (typically, there is option for this in PLAXIS)." 5sMyH[5zY
