DZ/T0276.19-2015岩石单轴压缩变形试验采用千分表法,岩石轴向位移控制0.1mm/min,0.001mm岩石纵向横向应变测量,通过测定岩石试样在单轴压缩条件下的纵向和横向应变值,计算岩石弹性模量、变形量和泊松比。绘制岩石单轴压缩应力-应变曲线。
→岩石强度:岩石抵抗压缩、拉伸、弯曲、剪切等单向作用的性能,岩石抵抗单轴压力破坏的最大能力为抗压强度。
→岩石软化系数:饱水岩石试样的抗压强度与干燥岩石试样的抗压强度之比(岩石饱水后,其强度降低,这种现象称为软化,用软化系数表示)。
→岩石弹性模量:岩石在弹性极限以内的单轴压力作用下,其应力和应变之比。
→岩石泊松比:岩石横向应变与岩石纵向应变之比。
