岩体的工程分类是岩体力学的基本问题之一.岩体工程分类的主要目的是,针对不同的工程对象,对岩体进行综合评价,划分等级,区分成性质相近的类别,为工程的选点,设计提供定量的资料.同时,岩体的工程分类也是我们按不同的类型深入研究岩体的力学性质,建立相应的数学模型的基础.因此岩体的工程分类具有重要的实际意义,对它的研究日益广泛地引起了人们重视.到目前为止,已提出了不少岩体的分类法.从不同的出发点大体分为两类,(1)从岩体力学出发对岩体特性的一般性分类,例如Muller的分类等.(2)为特定的工程目的分类,例如为岩石边坡的Goodman分类法等.为隧道工程而提出的岩体分类最早是Terzaghi(1946年)的分类法.后来还有Lauffer(1958年)等人提出的分类法.
The engineering classification of rock masses is one of the basic problems of rock mass mechanics. The main purpose of rock mass engineering classification is to comprehensively evaluate rock masses for different engineering objects, classify them, and classify them into similar categories, which are engineering Selecting points, designing and providing quantitative data. At the same time, the engineering classification of rock masses is also a basis for us to deeply study the mechanical properties of rock masses and establish the corresponding mathematical model. Therefore, the engineering classification of rock masses has important practical significance. The research on it has attracted increasing attention. So far, many classification methods for rock masses have been proposed. From different starting points, there are roughly two categories. (1) Starting from rock mass mechanics, the characteristics of rock masses General classifications, such as Muller’s classification, etc. (2) Classifications for specific engineering purposes, such as the Goodman classification of rock slopes, etc. The classification of rock masses proposed for tunnelling was first classified by Terzaghi (1946). Later, there was a classification method proposed by Lauffer (1958).
