Soil properties for short-term stability through SLIDE
Soil properties for short-term stability through SLIDE
(OP)
Hi all,
I am assessing the short-term stability of a road embankment.
To model short-term stability behavior, i have used the Undrained Shear Strength for cohesive soils.
How would you model a non-cohesive layer in Slide software? Would i be correct in simply using the Mohr-Coulomb c':0 , phi : 30 deg?
Thanks for your help!

Depending on whether it's a cut slope or fill slope, and whether it's NC, lightly OC or heavily OC, and the definition of short term (should be so short that less than 10% excess pore pressure is dissipated), using undrained strength for clay is not always safe.
For granular materials yes c'=0 and phi' are correct unless you are facing saturated fine sand in an earthquake event.
