岩体质量分类Q系统评述
首发时间:2005-07-25
摘要:1974年由挪威的巴顿提出的岩体质量分类Q系统,在许多国家都得到了应用,在我国地下洞室围岩分类、岩石地基、岩石工程边坡岩体质量分级等方面也得到了广泛应用。经过1993年、2002年两次修正,变得更加完善。它不仅适用于中低地应力条件,还适用于高地应力条件;不仅适用于硬质岩地区,还适用于软质岩地区。本文对岩体质量分类Q系统的发展过程、优缺点、Q系统与相关围岩分类方法的关系等进行了初步论述,重点介绍了2002年修正的Q系统。

A review on Q-system for the rock mass classification
Abstract:The Q-system for the rock mass classification which was proposed by Nick Barton, Norwegian in 1974 has been modified in 1993 and 2002 separately. Now it has been becoming more and more perfect, and was used in many countries all over the world. It is widely used in China in the surrounding rock mass classification of underground excavation, rock foundation, rock slope also. It not only can be used in the condition of low field stress, but also higher field stress. It is not only proper to the hard rock areas, but also to the soft rock areas. The process of development and the distinguishing feature of Q-system are discussed in this paper. The correlations of some methods for rock mass classification are discussed also. Specially, the Q-system modified in 2002 was introduced.
Keywords: rock mass classification Q-system surrounding rock mass classification of underground excavation correlations of some methods for rock mass classification Q-system modified in 2002
