【摘要】 选取不同吻合度结构面试样,进行干燥状态和饱和状态结构面抗剪强度直剪试验和JRC-JCS模型、 JRC-JMS模型经验估算。对比研究表明,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。更多还原

【Abstract】 Natural rock joints with different matching degree were selected as samples, and shear strength of them under dry and saturated conditions were measured by direct shear test and empirical estimated by the JRC-JCS and JRC-JMC joint shear strength models. Then, the test results of shear strength were compared with the empirical estimation results of shear strength. Comparison results show that the empirical estimation results of joint shear strength by the JRC-JMC model considering the matching degree are more exact than the empirical estimation results by the JRC-JCS model.更多还原
