| titleOfInvention | A kind of rock mass discontinuity three-dimensional roughness evaluation method |
| abstract | The invention provides a kind of rock mass discontinuity three-dimensional roughness evaluation method, comprise the following steps：Establish rock mass discontinuity 3-D geometric model, based on Delaunay Triangulation algorithm by rock mass discontinuity it is discrete be a series of triangle infinitesimals；The position that may be in contact when determining that shear action occurs for rock mass discontinuity according to shear direction, i.e., potential contact infinitesimal；Calculate total projection area of all potential contact infinitesimals of rock mass discontinuity on the face perpendicular to shear direction；The ratio between above-mentioned total projection area and rock mass discontinuity horizontal projected area are calculated, the ratio is used to describe rock mass discontinuity three-dimensional degree of roughness.Integrated structure face failure by shear mechanism of the present invention, obtain the roughness evaluation index with clear and definite theoretical foundation, the index not only reflects geometric shape of the structural plane on shear direction, consider the anisotropy of rock mass roughness, exist simultaneously with structural face shear strength and necessarily contact, can preferably service shearing strength appraising model. |
