Effects of the joint aperture and persistence on the shear behavior of coplanar non-persistent jointed rock masses and an improved Jennings shear strength criterion

Key Points

• Shear behavior depends significantly on joint aperture and persistence, influencing rock stability.
• The improved Jennings shear strength criterion shows notable accuracy in predicting outcomes across various conditions.
• Analysis focuses on coplanar non-persistent jointed rock masses under different variables, enhancing understanding of rock mechanics.
• Findings may indicate new approaches for engineering practices related to rock stability, particularly in mining or construction.
