| 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 |
