岩石加卸载变形特性及力学参数试验研究

Deformation characterslics of rock under loading and unloading conditions and experimental study of mechanical parameters

    摘要
  • 摘要: 通过加载和卸载两种力学状态的全过程应力—应变试验 ,揭示了岩体在加卸载时变形特性的差异 ,并结合试验结果 ,引入损伤力学概念 ,推导不同岩性岩石的损伤演化方程。

     

    Abstract: Through the stress stain test,the difference of deformation characters istics of rock under loading and unloading is found.At the same time,combining with the test results and introducing concept of damage mechanics, damage evolvement equations of rocks with different characteristics are derived in this paper.
