| 摘 要： | 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.

| Abstract: | Discussing the micro-cracks of brittle materials Griffith postulated have random orientation from the basic concept of his crack theory, this paper points out that there are following mistakes in some Chinese books in the field of rock mechanics. Firstly, Joints, bedded planes in rock are regarded as the random, micro-cracks,such as edges of molecules, crystal flaws, etc. Secondly, Griffith theory of strength is confused with Mohr strength criterion. Finaly , the possibility in application of Griffith theory of strength to rock mechanics and the direction of advanted study of the application are also discussed. |
