影响岩石强度的因素有很多,如岩石的组成成分、组构性质、围压以及温度等.文章对试验所得岩石主要化学元素与其抗压强度值进行灰色关联度分析,想找到岩石化学元素与其抗压强度的影响关系.通过研究它们之间的相关性,从而为岩石力学特性研究及工程实践提供参考.计算结果表明, O元素关联度相对较大,但从各项关联度数值整体分析来看,岩石内部化学元素对其抗压强度影响特征不明显.今后有望通过岩石内部化学成分(如SiO2、CaO等)对其抗压强度的影响分析,得到更为理想的结果.

There are many factors affecting rock strength, including rock composition, fabric properties, confining pressure and temperature. This paper studies the main chemical elements and compressive rock strength by grey correlation analysis. The correlation between rock’s chemical elements and compressive strength can provide some references for the research and engineering practice of rock mechanics properties. The results indicate that oxygen element has more effect than other elements. However, the chemical elements, from the whole integrated analysis, have no obvious effect on the compressive rock strength. More promising results can be obtained by analyzing the compressive strength effect of internal rock’s chemical elements (such as SiO2, CaO).
