摘要
为了研究裂隙条数和裂隙倾角对类岩石试样的力学特性的影响,对含多条裂隙的类岩石试样进行单轴压缩试验和数值模拟,并分析了数值计算结果,结果表明:当裂隙条数相同时,荷载方向平行于裂隙时试样的抗压强度大于荷载方向垂直于裂隙时试样的抗压强度;当荷载方向与裂隙间的几何关系保持不变时,随着裂隙的条数的增加,试样的抗压强度逐渐呈减小的趋势。
In order to study the influence of the number of fractures and the dip angle of fractures on the mechanical properties of rock like samples,uniaxial compression tests and numerical simulations were carried out on rock like samples with multiple fractures,analyzed the numerical calculation results.The results show that when the number of cracks is the same,the compressive strength of the specimen when the load direction is parallel to the crack is greater than that when the load direction is perpendicular to the crack.When the geometric relationship between the load direction and the crack remains unchanged,the compressive strength of the sample gradually decreases with the increase of the number of cracks.
