摘要：
In this paper, the method of calculating rock shear strength value, C,f with the M-robust estimate is presented, the calculating model and method are given. After the results calculated on the basis of in situ experimental data in Baiyun Ebo Mine is contrasted with the regression results obtained with the least square method it is shown that. The parameters which have been estimated by M-estimate method are more robust and reliability.
