It is well known that in the deformation and failure process of rocks,a rock system will constantly readjusts its structure to resist the external pressure when it develops to an unstable crack propagation period.
在岩石的变形破坏过程中,当进入不稳定的破裂发展阶段之后,系统不断调整结构抵抗外力的扰动,裂纹向局域集中的有序方向发展,应变能不断耗散,并以应变能的耗散为媒介,使系统与外扰动所追加的负熵流产生能量流通,也使系统熵值和系统的维数逐次降低,这一阶段岩石系统远离平衡态,岩石的破坏是系统熵的突变过程。
Based on the first and second law of thermodynamics and system theory,the relationship between the rock system state and entropy change was analyzed,and then rock entropy calculation method and mutation criterion were established based on the stress field distribution of rock system.
