摘　　要：根据生产爆破震动对山区山坡露天矿高陡边坡稳定性影响的工程实际,本文采用非确定性方法,将爆破震动引起露天矿边坡岩体移动变形这一现象视为一模糊事件,建立了生产爆破震动影响下山区山坡露天矿边坡岩体移动变形分析的Fuzzy测度理论模型。并利用该模型对我国某露天矿边坡岩体移动变形及其稳定性进行了具体的分析预测,所获理论结果符合工程实际。Based on results of the statistical analysis of a large amount of measured data in slope engineering,the fundamental fuzzy model of displacements and deformations of rock slope is established by using the theory of fuzzy measures.The formulas of two-dimensional problems are developed and applied to the prediction of the rock mass displacements and deformations due to surface mining.The agreement of the theoretical results with the field measurements shows that the model is satisfactory and the formulae obtained are valid and thus can be effectively used for predicting the displacements and deformations due to opencast mining and the slope failure under the influence of blast vibration.
