摘要
通过相似模拟实验研究开采引起的地表点下沉的动态变化规律,根据高精度的实测数据分析了地表点动态下沉曲线的统计分形特征。研究表明,地表动态下沉在一定的无标度区间符合自相似分形增长模式。同时,利用较少的测量数据实现了地表点动态下沉曲线的分形插值,在较高的精度范围内获得任意时刻地表点的动态下沉值,为揭示和预测地表下沉与变形的动态规律提供了新的途径。
The regularity of dynamic subsidence of ground surface point due to mining is studied by sireilar material model test, and the statistical fractal character for the dynamic subsidence curves of the ground surface point is analyzed by measured data with high accuracy. The research results indicate that dynamic subsidence of the ground surface point follow the fractal increment model in a proper non-scaling interval. The fractal interpolation in the dynamic subsidence curves of the ground surface point is realized by using less measured data, and the dynamic subsidence value of the ground surface point at any time is obtained in a certain precision. A new method of disclosing and predicting the dynamic subsidence and deformation of ground surface is provided.
