为了研究地表沉降预测的规律,分析常用的变形监测数据处理方法。文中结合某煤矿工业广场主井井架基础沉降监测数据,将灰色GM(1,1)模型与曲线拟合理论应用于井架基础沉降变形的数据分析,进行地表沉降预测结果的分析和检验,取得了较好的预测效果,并运用F检验法,对两种预测结果进行相关性分析,得出了合理选择预测模型的基本结论。同时文中也引用了已公开发表的沉降实测数据进行计算分析,印证了所用方法的正确性和科学性。
In order to study the law of surface subsidence prediction, the commonly used method of deformation monitoring data processing is analyzed. In this paper, based on the monitoring data of main shaft derrick foundation settlement in a coal mine industrial plaza, gray GM (1,1) model and curve fitting theory are applied to the data analysis of derrick foundation settlement and deformation, and the result of surface subsidence prediction is analyzed and tested. Better prediction effect, and use the F test method to analyze the correlation between the two kinds of prediction results, and get the basic conclusion of the reasonable choice of prediction model. At the same time, the paper also cites the published data of subsidence measured and calculated, confirms the correctness and scientificness of the method used.
