中文摘要：

按照Russenes和王元汉等人的岩爆经验判别准则,取硐室最大切向应力和岩石单轴抗压强度的比值、岩石单轴抗压强度和岩石单轴抗拉强度的比值、弹性能量指数作为地下工程岩爆的评判指标,利用国内外14个地下工程岩爆资料作为训练样本,建立Fisher岩爆级别判别模型,并对待判样本岩爆级别进行了预测。结果表明,所建Fisher岩爆判别模型的计算结果与实际情况吻合程度高,具有较强的判别能力。

英文摘要：

According to the judgement criterion of rock-burst of Russenes and Wang Yuanhan,the ratio of maximum tangent stress of chamber to rock uniaxial compressive strength,the ratio of rock uni-axial compressive strength to rock uniaxial tensile strength and the index of elasticity energy are determined to be the judging indexes of underground rock-burst,and fourteen real rock underground project examples at home and abroad are training samples to build a Fisher discriminant analysis model of rock-burst.Then it is applied in predicting the rock-burst level of the samples.The results showed that the calculating results by the Fisher discriminant analysis model of rock-burst agreed well with the practical records,showing an effective forecast ability.
