Mohr-Coulomb failure and landsliding

Landslides occur when driving forces, modified by slope and rainfall, overcome resisting forces, which depend on pore-fluid pressure and cohesive strength of the hillslope.

Learning Goals

• Understand Mohr-Coulomb failure
• Know the driving and resisting forces for landslides
• Understand the concept of “incipient failure”

Mohr-Coulomb Failure

The apprpoach used here, in which I compare driving (weight, slope) and resisting (frictional + cohesive - pore-fluid) stresses is called Mohr-Coulomb failure analysis.
