摘要岩石强度理论对不同尺度的岩石工程稳定性分析具有重要的理论意义与工程价值，其发展与岩石在不同拉压应力状态下的强度试验研究息息相关。尽管岩石在拉压应力的作用下强度特性差异很大，但目前对其强度理论及不同应力状态下强度试验的研究多关注三向受压应力状态。进行了如下系统综述：在阐述金属和土体相关强度理论的基础上，介绍岩石强度理论的发展历程及研究进展；与岩石强度理论发展相协调的不同拉压应力状态下岩石强度试验的研究现状；进而分析了现有岩石强度测试所覆盖的应力状态分区及9种岩石强度理论所定义的3个特征拉伸强度的区别；最后对岩石强度理论及不同拉压应力状态下岩石强度试验研究中尚未解决的问题进行讨论总结并对未来研究工作进行了展望。

Abstract：Rock strength criterion plays an important role in the multi-scale stability analysis for rock engineering in the theoretical and practical sense. The research progress on this topic depends on the experimental investigations of rock strengths subjected to different tensile-compressive stress states to a large extent. Despite the large strength differences under the tensile and compressive stresses，theoretical and experimental research efforts on rock strengths subjected to different stress states tremendously focused on triaxial compressive stress states. This paper provides a comprehensive review with respect to the following. The development history and research achievements of rock strength criterion were overviewed since the related work for metal and soil. The state of the art of the rock strength tests were summarized under different tensile-compressive stress states compatible with the development of rock strength criterion. The stress states covered by the current rock strength tests were further analyzed. The three characteristic tensile strengths defined by nine different rock strength criteria were also compared. Finally，the problems remaining to be solved were discussed and summarized on the theoretical and experimental researches of the rock strengths under different tensile-compressive stress states followed by the prospect of future research.

Key words： rock mechanics strength criterion stress state failure tensile
