摘　　要：在分析大量试验数据的基础上，探讨了页岩的层状结构面倾角和围压对其强度的影响。通过对各种现存强度理论与试验值的比较，分析了各种强度准则的适用性，提出了一种所需试验简单、数量少的强度准则模式。In this paper, the strength behavior of shale and especially the effect of lamination orientation on its strength have been investigated on the basis of a large quantity of data from uni and tri axial compression tests. The applicability of various strength criteria proposed by different investigators was examined for the tested shale by the comparison of theoretical and measured strength. A simple criterion has been suggested for such shale according to its features, in which parameters can be obtained only from uniaxial test and a couple of triaxial tests.
