摘要
利用有限元方法,分别对玄武岩在常温和高温下的单轴压缩试验进行了数值模拟分析,研究轴向荷载作用下玄武岩试样的受力特性。利用高温下玄武岩强度降低及其塑性变形较小的特点可以提高破岩效率。
By using the finite element method, the basalt uniaxial compression tests in normal and high temperature were simulated and the mechanical properties of basalt specimens were studied under axial load. The rock breaking efficiency can be improved by decreasing basalt strength and reducing its plastic deformation under high temperature.
