| Abstract: | ock quality designation ( RQD ) is one of the most important quantitative indices on estimating and classifying engineering rock mass, and its concept and theory have been developed significantly during last thirty years. On the basis of the research of its engineering application, we discussed some theoretic topics and proposed several new analysing methods in this note. |

| Keywords: | rock quality designation spacing of discontinuity threshold of spacing least effective scanline length |
