Unsaturated Slope Stability Analysis using midas GTS NX

Rainfall induced slope failure occur due to the reduction of soil shear strength as water infiltrate into the soil and then reduces its suction. However, the effect of rainfall and infiltration into the soil is most of the time ignored when designing slope above the ground water table. Due to the climate change, some part of the world suffer higher rainfall intensity which causes more rainfall-induced slope failure.

In this presentation, key aspect in analyzing unsaturated slope stability (input soil parameters for unsaturated soils, boundary condition, type of analysis) will be discussed and highlighted. The speaker will also discussed the advantage and disadvantage from different types of analysis.
