各向异性岩石抗压强度及弹性模量研究

Analysis of Compression Strength and Elastic Modulus for the Anisotropic Rocks

以糜棱岩为研究对象,制作三个方向的岩石样品,分别是平行面理平行线理方向(X)、平行面理垂直线理方向)(Y)、垂直面理线理方向(Z),对其进行单轴压缩试验。结果表明:糜棱岩抗压强度具有明显的各向异性特征,从高到低依次为Z方向>Y方向>X方向;糜棱岩弹性模量具有较明显的各向异性特征,从高到低依次为X方向>Y方向>Z方向。该结果不仅增加了人们对各向异性岩石的力学性质的认识,同时也为工程建设提供了一些指导意义。

This research targets on the mylonite and make samples in three directions:parallel to foliation and lineation(X),parallel to foliation and perpendicular to lineation(Y)and perpendicular to foliation(Z),uniaxial compression test for these rocks are completed.The results show that compression strength and elastic modulus of mylonite are anisotropy,compression strength from high to low is Z>Y>X while elastic modulus from high to low is X>Y>Z.This study not only increases the understanding of the mechanical properties of the anisotropic rocks,but also provides help for engineering construction.
