| 摘 要： | 以某工程边坡中的岩体结构面为研究对象,为得到较合理的抗剪强度参数,分别使用携剪试验和JRC-JCS模型得到两种参数,然后在对比分析各实验结果的基础上综合取值.结果表明,携剪试验受取样制约,所得抗剪强度值大于实际,而JRC-JCS模型利用现场回弹仪试验和结构面实际粗糙值,所得强度值更接近实际.

| Abstract: | This article studies the rock joints of an engineering slope.Both the JRC-JCS model and the shear test were used to obtain reasonable shear strength parameters.The final parameter is resulted from the synthetic analysis of the two results.The shear strength value from the shear test exceeds the reality,due to its sampling,and that from the JRC-JCS model is closer to the reality with the spot rebound Hammer test used and the actual surface roughness considered. |
