岩石力学性质的影响因素分析

室内岩石力学实验作为岩石力学性质分析的有效手段之一，已逐渐被国内外学者广泛使用。但是，由于岩石力学试验仪器、微裂隙、孔隙等各因素的影响，同组岩石样品力学参数数据结果相差较大。如何排除或减少各类影响因素造成的结果偏差，以合理的确定岩石力学性质，是岩石力学实验研究的重要内容。本文根据胶西北山东黄金4000m深钻岩石样品获得的室内劈裂、单轴和三轴试验结果，结合岩样破裂方位、方式及强度特征，分析了微裂隙、孔隙率（孔隙）、围压、岩样实验时所受摩擦力4类因素对室内岩石力学性质的影响，研究结果可为室内岩石力学试验数据的选取工作提供参考。

ANALYZING THE INFLUENTIAL FACTORS OF ROCK MECHANICAL EXPERIMENT

The laboratory experiments of rock mechanics, as one of the most effective methods to analyze the mechanical property of rocks, had already used widely by scholars at home and abroad. However, various influence factors, such as experimental instruments, developmental microfissure, porosity and so on, made rock mechanical parameters were different. This paper collected 4, 000m deep drilling in Northwest Shandong Gold Mine, and mainly analyzed the influence of rock mechanical property caused by microfissure, porosity ratio, surrounding rock and fiction of rock sample tested. The analysis based on the results of split test, axial tests and triaxial tests, combined with the fracture orientation, the way of failure and strength character. The results of this study could provide theoretical basis for rock mechanics tests.
