图1表示某露天铁矿最终边坡理论化了的地质剖面,并已分析了该边坡的稳定性。最终边坡的至高点标高488米,边坡倾角45°,根据48个岩芯试件的三轴试验已求得了其残余剪切强度(C,φ值)。初期地质力学研究包括用均质岩石材料建立的整个边坡模型,48个试件可视为一数群的随机变量。C和φ变量的相关系数(ρ)是ρ=-0.34。不出所料,这说明相关性不好。 Figure 1 shows a theoretical section of a theoretical slope at a certain open-pit iron mine and the stability of the slope has been analyzed. The final elevation of the slope is 488 meters above sea level and the inclination of the slope is 45 °. The residual shear strength (C, φ) has been obtained from the triaxial tests of 48 core samples. Initial geomechanical studies include the entire slope model built with homogeneous rock materials, and 48 specimens can be considered as a random variable of a population. The correlation coefficient (ρ) for the C and φ variables is ρ = -0.34. Unsurprisingly, this shows a poor correlation.
