摘要为更好地理解矿物种类与颗粒粒径对岩石力学性质的影响，以4种大理岩为研究对象，首先获得矿物成分、矿物微观力学性质、颗粒粒径及形状等基础数据，接着对它们的强度参数、变形性质及破坏模式进行试验测试，最后进行综合分析。结果表明：(1) 郴州、房山、Carrara、贺州大理岩强度逐渐减小，延性逐渐增强，即白云石大理岩的强度与脆性都强于方解石大理岩；(2) 只考虑颗粒粒径因素时，岩石强度与脆性随着粒径的增加而减小；综合考虑其他因素时，存在粒径大的岩石强度大、脆性强(延性弱)的可能；(3) 黏聚力与单轴压缩强度关联性强，二者正向线性相关，黏聚力与抗拉强度关联则较弱；(4) 单轴抗压强度与抗拉强度的比值与受压条件下的Griffith理论预测值误差较大，而起裂应力与抗拉强度的比值则稳定在7～12范围；(5) 三轴压缩试验中当围压上升至设定围压后，围压在小范围内变化的趋势与轴向应力变化在整体上具有同步性。这些成果不仅加深了对矿物粒径效应的认识、丰富了岩石力学理论知识，也为将来的大理岩工程评估及计算分析提供大量基础数据。

Abstract：To understand the effect of mineral composition and grain size on mechanical properties of rock better，the basic data of mineral composition，mineral micro-mechanical properties，grain size and shape of four kinds of marble are obtained in this paper. Then their strength parameters，deformation properties and failure modes are tested for further analysis. The results indicate that：(1) The strength of Chenzhou，Fangshan，Carrara and Hezhou marble decreases while their ductility increases in sequence，that is，the strength and brittleness of dolomite marble is greater than that of calcite marble. (2) Considering only the effect of grain size，the strength and brittleness of rock decreases with increasing grain size. However，when considering other factors(mineral composition，micro-mechanical properties) together，it is possible that rocks consisting of larger grains present a higher strength and more brittle behavior. (3) The cohesion of rock is positively and linearly correlated with uniaxial compressive strength，while it is weakly correlated with tensile strength. (4) The ratios of uniaxial compressive strength to tensile strength are significantly different from that predicted by the extended Griffith theory，while the ratios of crack initiation stress to tensile strength maintain around 7–12. (5) During triaxial compression test，the confining pressure fluctuates slightly above the target value，and the overall synchronization exists between the variation of the confining pressure and the axial stress. The results not only enhance the understanding of mineral grain size effect and enrich the theoretical knowledge of rock mechanics，but also provide a large number of basic data for further marble engineering evaluation and calculation analysis.
