Other AbstractIn light of the importance of study of mechanical parameters of rock mass structural plane, based on a large number of practical projects and the basic statistical principle about error analysis, the applicabilities of least square method and M - estimation method for calculating the structural plane shear strength parameters, are studied. The results show that, when the gross errors are uncertain, it is hard to find the regularity that the two methods are more suitable for some certain condition. Because the data all have the given engineering characteristics, in order to make results more accurate, a new method based on the above two methods is proposed; and it is applied to calculate shear strength parameters of Lijiahe reservoir.
