| Abstract: | The shear strength of rock mass of Xiaolangdi Dam is investigated herein. In order to determine the parameters, intact rock compression test in the laboratory, surveying and sampling of geometric characteristics of joints are conducted. Engineering geological comparison method, analytical method and Hoek-Brown criterion based on the RMR classification are used to estimate the shear strength. These methods are reviewed as well. It concluded that various methods and engineering judgment are suggested in order to obtain reasonable mechanical parameters for design. |
