根据工程实际,应用模糊数学的Fuzzy测度模型,将复杂条件下开采地表移动变形问题视为一模糊事件,对煤矿开采引起的地表移动变形问题进行了分析研究,推导了相关的地表下沉、水平变形、倾斜及曲率的理论计算公式,同时利用BP神经网络方法确定了模型的相关参数。通过工程实例应用分析表明,该方法所得的理论结果与实际情况相符合。
According to the engineering practice, the fuzzy measure model of fuzzy mathematics is adopted to treat the movement and deformation of surface under complex conditions as a fuzzy event. The problem of surface movement and deformation caused by coal mining is analyzed, and the related surface subsidence, Deformation, tilt and curvature of the theoretical formula, using BP neural network method to determine the parameters of the model. The application of engineering example shows that the theoretical result obtained by this method is in accordance with the actual situation.
