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
