本文从格里菲斯强度理论的基本概念出发,讨论了该理论所指的微小裂隙分布是随机的,从而根据公式推导得出国内一些岩石力学专著中在应用格氏理论时有以下错误:1.把岩石中的节理、层理等视为那些杂乱无章的微小裂隙,如颗粒边界、晶体缺陷、晶洞等,2.把格氏强度理论和莫尔强度理论混淆起来。最后,本文还讨论了格氏理论在岩石力学中应用的可能性和进一步研究的方向.
Based on the basic concept of Griffiths intensity theory, this paper discusses that the distribution of tiny cracks in this theory is random, and deduces from the formula that some of the domestic rock mechanics monographs have the following errors when applying the theory of Grignard: 1 Think of the joints, bedding, etc. in the rock as tiny, disorganized fractures such as grain boundaries, crystal defects, craters, etc. 2. Confuse the theory of Grignard strength with the theory of moire strength. Finally, the paper also discusses the possibility of the application of Grignard theory in rock mechanics and the direction of further research.
