摘　　要：在大量的试验基础上探讨了页岩的层状倾角和围压对其强度的影响通过对各种现存强度理论公式与试验值的比较，分析了各种强度准则的适用性，提出了所需试验简单。Based on a comprehensive series of triaxial and uniaxial compression tests on the Shale, its strength behavior has been investigated, especially the effects of lamination orientation on its strength, in this paper The applicability of various strength criteria proposed by different investigators was examined for the tested Shale by the comparison of results between strength of theories and tests And a single criterion has been suggested for such shale according to its special feature, in which parameters can get from only uniaxial test and a couple of triaxial tests

关 键 词：页岩 层状倾角 强度异性 强度准则
