摘　　要：通过建立Fuzzy测度模型,推导出软岩地层露天开采地表下沉和水平移动计算公式,并利用该模型对软岩地层露天开采地表移动的实例进行了分析,理论预测结果与实测数据相吻合,满足工程需要。Analysis method of the surface displacement due to open-pit mining in soft strata is given. And the fundamental fuzzy model is established by using the theory of fuzzy measures in the paper. The theoretical formulas for the prediction of the ground subsidence and horizontal displacement are given. The agreement of the theoretical results with the measured data shows that the model is satisfactory.
