岩体工程分类可以作为工程目的而估计岩体情况的重要方面。本文作者提出一个新的方法,它与目前在隧道工程中广泛应用的一些方法,例如Wickham等(1972)的RSR概念,Beiniawski(1973)的地力学分类和Barton等(1974)的Q系统,不同之处在于如何对岩体进行综合评价,虽然在岩体特性的基本因素的考虑上并无大的不同,我们的分类方法是考虑到岩休物理力学参数的一定的不确定性而基于模糊数学的概念得到的,本文的目的是进一步阐述这个方法,并把岩石参数分为间隔指标和名义指标。最后给出了实例。
The rock mass engineering classification can be used as an engineering objective to estimate the important aspects of the rock mass condition. The author of this paper proposes a new method which is different from some methods currently widely used in tunnel engineering, such as the RSR concept of Wickham et al. (1972), the geomechanical classification of Beiniawski (1973), and the Q system of Barton et al. (1974). The point is how to comprehensively evaluate the rock mass. Although there are no major differences in the basic factors of rock mass properties, our classification method is based on fuzzy mathematics, taking into account the certain uncertainty of rock physical and mechanical parameters. The concept was obtained, and the purpose of this paper is to further elaborate this method and to separate the rock parameters into interval indicators and nominal indicators. Finally gives an example.
