摘要:

Barton于1974年首次提出了岩体质量分级Q系统,在许多国家得到了广泛应用,经过多次修正、完善,现已成为目前国际上最流行的岩体分级系统之一。文章基于2002版Q系统的支护设计,并结合某地下储油洞库工程应用实例,验证了Q系统可成功地应用于地下储油洞库,并在实际工作中,就Q系统应用时的具体参数取值遇到的问题进行了合理解释。工程伊始,同时采用RMR系统和Q系统2种岩体质量分级系统,可建立Q与RMR的关系式,利用RMR系统确定岩体自稳时间,从而为合理确定支护施作时间提供指导,为保证应用Q系统的正确性,建议有经验的地质工程师在现场对岩体质量进行评价。

Abstract:

Rockmass classification Q system, which has been widely used in many countries, was firstly presented by Barton in 1974. It has been one of the most popular rockmass classification systems in the world. The support design based on Q system of 2002 edition is introduced in summary, the applicability of the Q system in an underground oilstorage cavern is testified, and reasonable explanation for detailed parameter selection is given In the beginning of the project, both RMR system and Q system are used, the correlation between Q system and RMR system is established and the rock mass standup time is determined on basis of RMR system It is proposed that experienced geological engineer should make evaluation on the rock mass quality on the site, in order to ensure the validity of the application of Q system.

Key words: rockmass classification, Q system, underground oilstorage cavern, support design, standup time
