| 摘 要： | 由于煤炭开采而形成的塌陷区地形形态复杂,本文利用分形插值理论模拟了塌陷区地形。在Matlab语言环境下,实现了塌陷区基于遗传算法求取无标度区最优解和基于FBM分形插值算法,在此基础上求解分形特征参数H和σ。对概率积分法预计的数据进行分形内插绘制地表下沉图,取得了理想的效果。

| Abstract: | The terrain in the subsided area generated by mining is complicated, in this paper, we apply fractal interpolation to simulate the fractal terrain in the subsided area. In Matlab, we achieve the optimal solution in scaleless band based on the Genetic Algorithm and the fractal interpolation method based on FBM in the subsided area, and thus making out the fractal characteristic parameters H and σ. The ideal result is achieved by employing the data estimated with the probability integral method and the ground pressure figures are drawn. |
