岩体结构面不同剪切方向的抗剪强度模拟试验研究

Study on Shear Strengths of Rock Structure Planes in Different Shearing Direction by Simulation Experiment

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。

In order to simulate simulate rock structure planes with directional characteristic, some concrete specimen were made. The shearing experiments along different direction were made on the concrete models,and a series of data was obtained. By regression analysis of the experimental data, an empirical formula experiential that related shear strength of joint plane to shear direction was set up, and then the changing law of shear strength of rock joint plane with shearing direction was concluded.
