摘　　要：本文通过室内直剪试验和三轴压缩试验研究了常见节理岩体类型的抗剪强度特征后,提出用抗剪强度“结构影响函数”来描述岩体结构对节理岩体抗剪强度的综合影响和用结构影响函数法来确定节理岩体的抗剪强度。该方法较现场试验法要简便、迅速、经济。After studying the characteristics of the shear strength of some common kinds of jointed rock masses by direct shear tests and triaxial compression tests, it is suggested that a structure affec- tion function can be used to express the synthetical effects of the rock mass structure on the shear strength of jointed rock mass and that the shear strength of jointed rock mass can thus be determined by the structure affection function method. This method is more convenient than the field test method.
