| 摘 要： | 选取不同吻合度自然节理试样,进行干燥状态和饱和状态的JRC-JCS模型和JRC-JMS模型试验研究。结果表明,在节理粗糙度系数的定向统计测量和尺寸效应分析,以及剪切过程衰减折减的基础上,运用JRC-JCS模型综合评价节理抗剪强度可靠性较好,考虑吻合度系数的JRC-JMC模型比JRC-JCS模型具更好的预测能力。 |

| Abstract: | This paper presents a comprehensive experimental evaluation of rock joint shear strength.The test specimens are natural rock joints and have differential anastomotic degrees.The paper presents the tests for the JRC-JCS model and the JRC-JMS model in drying and saturated conditions.The test results show that the comprehensive evaluation of rock joint shear strength by the JRC-JCS model has a good reliability on the bases of the directional statistical measurement,the analysis of JRC scale effect,as well as the consideration of reduced JRC during shearing.The JRC-JMC model considering anastomotic degree can better predict the rock joint shear strength than the JRC-JCS model. |
| Keywords: | Shear strength Rock joints Comprehensive evaluation Joint roughness coefficient JRC Experiment Rock mechanics |
