摘　　要：从可以反映小尺度力学性质空间变异性的随机场出发 ,借助现代物理学逾渗 (Percolation)临界理论 ,推导了用有限个小尺度岩体试块抗剪试验结果确定高坝基础岩体宏观抗剪强度的上、下限理论计算公式 .研究结果表明 。By the application of the theory of random fields and precolation theory, the paper deduced theoretical formulas for the upper and the lower limit of the macro_shear strength of rock masses which just need a finite group of shear strength test results gained by the small specimens commonly used in engineering. The result shows that the macro_shear strength of rock masses is in values between the arithmetic mean of the whole small dimensional shear strengths and the average of these small dimensional strengths which are less than the population mean.
