Influence of intermediate principal stress on the fault strength

Physics of Fluids
Earthquake risk assessment of fault often overlooks the influence of intermediate principal stress (σ2) on fault. However, recent studies have shown that σ2 can alter the internal friction angle, which in turn affects the friction coefficient and strength of rock.

Influence of the Intermediate Principal Stress on Sandstone Failure

Rock Mechanics and Rock Engineering, 2019
This paper reports the results of fracture testing of sandstone under constant minor principal stress (20 MPa) and various intermediate principal stresses. The results show that when the minor principal stress is constant, as the intermediate principal stress increases, the ratio of the octahedral shear stress (τoct) to the octahedral normal stress ...

Strength characteristics of brittle rocks under multi-stage intermediate principal stress loading

Géotechnique Letters, 2022
A series of single-stage true triaxial compression (TTC) tests and multi-stage intermediate principal stress (σ2) loading tests were carried out on three types of brittle rock specimens in this study to examine the influence of σ2 and the validity of obtaining strength parameters by using a multi-stage loading method under true triaxial stress ...

Strainburst process of marble in tunnel-excavation-induced stress path considering intermediate principal stress

Journal of Central South University, 2019
Strainburst is one type of rockburst that generally occurs in deep tunnel. In this study, the strainburst behaviors of marble specimens were investigated under tunnel-excavation-induced stress condition, and two stress paths were designed, a commonly used stress path in true triaxial unloading rockburst tests and a new test path in which the ...

The modified Mohr-Coulomb model considering softening effect and intermediate principal stress

Mechanics of Advanced Materials and Structures
Based on the Mohr-Coulomb model, a modified Mohr-Coulomb model that can consider both softening effect and intermediate principal stress effect was formed by introducing plastic internal variables that characterize material damage and a modified stress ...
