摘要1980年E. Hoek和E. T. Brown提出了Hoek-Brown(H-B)强度准则，已充分得到岩石力学与工程研究者的认同，并进行研究和应用。首先系统地阐述H-B强度准则研究进展：E. Hoek和E. T. Brown对H-B强度准则的研究成果、三维H-B强度准则、H-B强度准则岩石和岩体参数研究、考虑层状节理的H-B强度准则及其参数的各向异性研究。再对过去30 a国内外基于H-B强度准则工程应用的成果进行总结。最后对笔者所开展的H-B强度准则最新研究工作进行介绍：提出一种真正意义上的广义三维H-B强度准则，并采用3种Lode角函数进行屈服面修正，使其可以直接应用于后续本构模型建立和数值软件嵌入；采用三维颗粒流模型进行微观数值建模，对H-B强度准则岩石和岩体参数开展微观研究并建立多尺度联系，为参数的确定提供更加可靠的依据。
Abstract：E. Hoek and E. T. Brown proposed the Hoek-Brown(H-B) strength criterion in 1980. This strength criterion is now widely accepted and studied by researchers and engineers in rock mechanics and engineering field，and is now widely applied to rock mass engineering. In this paper，a systematic review is performed on the progresses of the H-B strength criterion firstly，which are the work by E. Hoek and E. T. Brown，the studies on the three-dimensional H-B strength criteion，the parameters used in this criterion，and the criterion related to anisotropy of rocks with layered joints. Then，the applications of the H-B strength criterion during the past 30 years to different rock mass engineering problems were reviewed. Finally，the progresses of the H-B strength criterion carried out by the authors are introduced. A generalized three-dimensional H-B strength criterion has been proposed and modified by utilizing three different Lode dependences，so it can be directly applied to construct constitutive model and be embedded in numerical software. Based on three-dimensional numerical simulations with particle flow model，the parameters of rock and rock mass used in H-B strength criterion are studied in microscopic scale and a multi-scale relationship is found for providing a more reliable basis for determination of these parameters.
