在AutoCAD中实现三维地层模拟的一种方法
|
摘要
以地层等高线和地质柱状图为建模基础信息,采用曲面样条函数进行插值计算地质曲面,并对A u toCAD进行二次开发,将二维抽象的等高线信息以三维可视化的图形效果在A u toCAD的图形窗口中直观形象地表示出来,为开采和规划决策提供依据。此方法可使煤矿主采区域、城市活断层探测以三维地层显示,对煤矿行业,地震活断层研究有一定的参考价值。
Base on fundamental information, counter line of stratum and geological profile, for model setting up, a geological surface is interpolatively computed by using spline functions of curved surface. Furthermore, secondary development is made to AutoCAD, display abstract 2 dimensions counter line information directly with a visible 3 dimensions figure, which facilitates for mining and planning. This method can display main mining area and active faults in a city in 3 dimensions figure, useful for mining and active fault in a city.
