摘要
根据磷矿露天开采工程实际,采用Fuzzy测度理论,将开挖引起岩体边坡移动变形这一客观现象视为一模糊事件,依此建立了边坡岩体移动变形预测分析的Fuzzy测度模型。利用所建模型对已有的矿山边坡岩体移动参数进行了反分析,并对露天边坡移动变形及其稳定性进行了具体的分析,所获结果符合工程实际。
Based on results of the statistical analysis of a large amount of measured data in slope engineering, the ftmdamental fuzzy model of displacements and deformations of rock slope is established by using the theory of fuzzy measures. The agreement of the theoretical results with the field measurements shows that our model is satisfactory and the formulae obtained are valid and thus can be effectively usd for predicting the displacements and deformations due to opencast mining and the slope failure under the influence of groundwater.
