摘要
通过建立单轴压缩情况下含裂纹岩石试件的功能平衡方程,运用概率统计的方法,推导了岩体弹性模量尺度效应的表达式,揭示了岩体弹性模量尺度效应的内部结构本质。
By using statistical method and establishing work-energy equilibrium equation, the authors have developed an expression describing the size effect of Young's modulus for rock under unixial compression.The construction nature of size effect of rock is revealed in this paper as well.
