【摘要】 为了解决复杂地形数值建模现有方法存在的不足之处,采用MATLAB软件编程并基于矿区数字地形图,对复杂地形数值建模方法进行了研究,提出了一种3DEC数值模型建模新方法。研究结果表明:对任意复杂的矿区地形条件,该方法均可适用,通过实践可知,该方法智能化程度较高,建模速度较快,主要操作步骤全部采用程序模块进行处理,能自动绘制三维地表图形、自动输出相应格式的数据文件。在样条插值过程中,可人为设定横向和纵向插值距离,以控制地表模型与实际地形的偏差。可通过将所建数值模型与MATLAB所绘三维地表图形进行对比,检验所建模型的可靠性。如果将相应程序模块稍加修改,便可将此方法应用到FLAC^3D及其他数值模拟软件的模型创建中。更多还原

【Abstract】 In order to solve the shortcomings existed in available method to establish a numerical model of complicated terrain,a Matlab software programming based on the digital terrain map of the mining area was applied to the study on the method to establish the complicated terrain numerical model of mining area. A new method to establish a 3DEC numerical model was provided. The study results showed that the new method could be applied to the complicated terrain condition in any mining area. The practices showed that the method was high in the intelligent and fast in the modeling speed. The major operation procedures all were handled with the program module. The 3D surface graphics could be automatically drawn and the relevant format data documents would be automatically output. In the spline interpolation process,the distance between the lateral and longitudinal spline could be set up artificially in order to control the deviation between the surface model and the actual terrain. A comparison could be conducted between the established numerical model and the 3D surface graphics drawn with Matlab software and the reliability of established model was approved. Once the relevant program module could be slightly modified,the method could be applied to model established with the FLAC^3Dand other numerical simulation software.更多还原
