摘 要:岩体分类是工程岩体力学中很重要的一种辅助设计手段.迄今为止,我国矿业界一直延用俄国学者普氏于本世纪初提出的f系数来评价岩体的强度特性.这一方法早已不适用.本文对这种方法的缺点作了分析,论述了岩体分类的基本原则,介绍了世界上普遍应用的几种岩体分类方法,提出了自己的见解和方案.In engineering rock mechanics, rock mass classification is one of the important assistant approaches to engineering design. To date, the coefficient f, which was first introduced by a Russian scholar,M.M. Protodyakonov in 1907, has still been used in China to describe the strength characteristics of rock mass. But it has already been no longer suitable. In this paper, the disadvantages of this method are analysed, the basic principles of rock mass classification discussed, popular rock mass classificaton systems applied in the world introduced, and new ideas and a suggested system presented.
