【摘要】 采用模糊数学综合评判方法，选取影响岩爆的一些主要因素，例如地应力大小、岩石抗压和抗拉强度、岩石弹性能量指数，对岩爆的发生与否及烈度大小进行了预测。针对国内外一些岩石地下工程实例进行了分析计算，结果与实际情况符合得很好，说明岩爆预测的模糊数学综合评判方法的有效性。更多还原

【Abstract】 The method of fuzzy comprehensive evaluation is used to predict whether rockburst will happen in the underground rock projects and how much the intensity of rock burst is. Some main control factors of rockburst, such as the values of in situ stresses, the compressive and tensile strengths of rock, the elastic energy index of rock, are chosen in the analysis. A series of underground rock projects at home and abroad are evaluated with the proposed method. The evaluated results agree well with the practical records, which shows that the proposed method is effective in prediction of rockburst.更多还原
