摘要
地下矿产被采出后引起的地表沉陷是一个时间和空间的非线性变化过程。文中以Knothe时间函数建立的地表移动动态预计算法为基础,并运用MATLAB中的图形用户界面(GUI),通过窗口、菜单、控件等构成操作简便的用户界面,实现主断面和任意点的动态预计的可视化。
The subsidence of earth surface incurred by underground mining is nonlinear variations of space and time. On the basis of the dynamic prediction-algorithm of the ground movement created by Knothe time function, applying to graphical user interface （GUI） of MATI.AB and by the mean of easily-operated user interface constituted by window, menu, control, the dynamic prediction visualization of main section and arbitrary point was investigated and realized in this paper.
