【摘要】 通过单轴压缩试验研究了岩石强度,并用空间弹性力学理论进行分析比较,采用高频振动疲劳试验研究了岩石的疲劳强度,得出了试验中所用材料603号花岗岩的纵向应力-应变曲线以及疲劳强度区间,并对其疲劳现象进行了分析。更多还原

【Abstract】 This paper studies the strength of rocks through uniaxial compression tests and makes analysis and comparison on the results using elasticity theory. In testing, the high-frequency vibration technique is used to fatique the rock specimens. The longitudinal stress-strain curve and the fatique strength range of 603 granite material have been obtained and the fatique phenomenon of the material is analysed.更多还原
