用混凝土模具模拟具有方向性的岩石节理面,并在剪切仪上沿不同方向进行剪切试验,测得一系列数据,通过回归分析,建立了节理面抗剪强度与剪切方向角之间的经验公式,总结出了具有方向性的岩石节理面抗剪强度随剪切方向角的变化规律。
A concrete model was used to simulate the rock joints with directionality. Shear tests were performed in different directions on the shear. A series of data were obtained. Through regression analysis, the relationship between the shear strength and the shear angle was established The empirical formula of the rock mass is summarized, and the law of the shear strength of the rock joint surface with the shear direction angle is summarized.
