CORRELATIVITY OF ROCK INHOMOGENEITY AND ROCK BURST TREND
岩石非均质性与冲击倾向的相关规律研究

The index E/l of rock burst trend is an import parameter which reflects possibility of rock brust,type of rock burst and intensity of rock burst. Based upon a great deal of numerical tests,the stress-strain curve of inhomogeneity rock is studied. It is found that the relation of rock burst trend index E/l and inhomogeneity parameter m is exponential function,and rock burst trend index decreases as inhomogeneity parameter m increases.
