| Abstract: | In order to obtain influence laws of different initial damage on rock mass mechanical properties,damage laws for fracture sample in different stages are studied based on uniaxial compression test.Mechanical properties are studied by quantitative analysis or qualitative analysis according to the difference of initial damage and the difference of distance for fractured surface.Empirical formula under the condition of certain fracture scale are given.It is important for security and stability of engineering ro... |
