Effect of intermediate principal stress on the stability of slopes [PDF]
Archives of Civil EngineeringThe intermediate principal stress (σ2 ) effect is a mechanical property inherent in many rock and soil materials. However, the effect of σ2 is often ignored in slope stability analyses, and its impact on slope stability is seldom investigated.

Failure criterion for soft rocks considering intermediate principal stress
International Journal of Mining Science and Technology, 2021 The significant differences between hard rocks (more brittle) and soft rocks (more ductile) may suggest the use of different failure criteria. A strength criterion for soft rocks that includes intermediate principal stress was proposed. The new criterion
