大理石中矿物优选方位对石材抗压强度的影响

本文通过几种不同类型的大理石中矿物晶体优选方位的岩组分析，并根据其组构特征选择石料的切面方向，得出了矿物排列方向影响石材抗压强度的肯定性结论；反映了进行岩石结构构造研究在石材加工中的意义；论证了利用大理石中矿物优选方位来确定石材锯极方位以获得较大抗压强度的可行性；提出石材加工中注重岩石内部结构研究的必要性。

The Consequence of Minerals Optimum Direction in Marbles to Compressive Strength of Stone Materials

In this paper,we confirm that the way of the range of minerals influence stone materials compressive strength,by the petrofabric analysis of minerals crystals optimum direction in several types of marbles and the study on choosing tangent place direction of stone materials based on their fabric feature. We also demonstrated the feasibility to get a cutting direction,that the larger compressive strength can be available,according to the minerals optimum direction in marbles.It suggests the significance of reaching on stone materials structure on processing of stone materials.
