岩石内部各种微裂隙的产生及发展
导致岩石的物理力学性质的劣化
此即损伤对岩石作用的结果。本文根据大理岩破坏过程中裂隙扩展的作用
定义了视损伤变量D=ε_v~k/ε_v~m
并导出了岩石的应力-应变关系和损伤变量D与D的关系。通过损伤试验
得出与理论值相吻合的结果。
The initiation and propagation of all kinds of micro-fissures in rock results in the weakness of physical-mechanical properties of rock
which is the effect of damage to rock. The pseudo-damage variable (
) is defined according to the effect of fissure propagation to marble during Its rupture process. The relationships between stress and strain
and between damage factors D and D are derived. The results of damage testing is well tallied with theory results.
