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。

Rockmass 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 rockmass 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 oilstorage 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 standup 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.
