| Abstract: | Stability of rock engineering is greatly affected by joints.The shear strength of the joints is a controlling parameter in analysis of rock mass stability.In this paper,authors presented an average slope method for a quick and an accurate estimate of shear strength of joints,based on review of the JRC-JCS model and several other existing methods.Its advantages over other methods were demonstrated by case studies. |

| Keywords: | Joint Empirical estimation of shear strength JRC-JCS model Average slope method |
