各种岩体分类中,无论是以定性为主的分类,还是以定量判据为主的分类,都要涉及到岩体的完整性问题。岩体的完整性,是表征岩体强度,岩体变形性的重要标志之一。长期以来,国内工程地质界都以直接影响岩体完整性的节理裂隙的特性来说明岩体的工程性状,其中尤其常用的是节理裂隙的间距。可是,国内外至今没有统一的方法和标准。
In all kinds of rock mass classification, regardless of qualitative classification, or classification based on quantitative criteria, the integrity of rock masses must be involved. The integrity of the rock mass is one of the important indicators of the strength of the rock mass and the deformability of the rock mass. For a long time, the engineering geologic circles in China have used the characteristics of joint cracks that directly affect the integrity of rock masses to illustrate the engineering properties of rock masses, and in particular, the spacing of joints and fissures is commonly used. However, there are no unified methods and standards at home and abroad.
