摘要
地质构造等值线中,断层一直没有很好的处理方法,本文选用一组基函数,采用最小二乘法对离散的空间点进行拟合,在此基础上生成等值线。根据断层数据采用二阶导数及三次样条拟合等方法处理加入断层后的等值线。经检验与实际情况较符合。
There is not a perfect method to draw isoline in geological structure with fault. This paper uses a set of primary functions and least-square procedure to fit a surface according to sets of scattered data based on which the software can draw isoline. This paper also uses second derivative and fitting cubic spline according to fault data to treat isoline while fault is added to geological structure. It fits the actual instance well.
