THE ANALYSIS ON RELIABILITY OF INDEX OF SHEAR STRENGTH OF ROCK
岩石抗剪强度指标的概率分析

In the article the correlation is analysed between shear parameters of rock f and c interms of Coulomb's law.The unite distribution of two dimentional random variables isused to deduct reliable probability of the parameters for comparing object values in different design stages and elevating reliablity of shear parameters of rock.
