摘　　要：结构面对工程岩体的稳定性有着决定性的影响,结构面的抗剪强度参数是分析岩体稳定的关键的参数。本文回顾了结构面抗剪强度估算的JRC-JCS模型及其估算方法,提出了可快速估算结构面抗剪强度参数的平均斜率法,并通过对比分析阐明平均斜率法的优越性。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.
