【摘要】 在地质层面建模和等值线的网格化中,网格节点插值是一个不可逾越的过程。断层约束下的插值算法研究,对带断层的地质层面建模和等值线绘制有重要的意义。目前在多数情况下断层信息不全,一般仅有断层的平面投影信息,没有高程、断距、倾角等信息,这不利于带断层的地质层面建模和等值线图绘制。本文提出了一种断层约束下的插值方法,该方法是对断层轨迹法的有效改进。算法仅需断层的平面位置信息,能有效地解决断层约束时的高程插值问题。最后,通过算例验证了该算法的有效性。更多还原

【Abstract】 In geological surface modeling and contour gridding, the interpolation of the grid nodes is an essential process. Therefore, the research on interpolation algorithm constrained by faults has great importance for geological surface modeling and contour mapping. However, in most cases the fault information is incomplete. Usually it only includes the plane projection information of faults, while there are no other information of the altitude, the displacement, or the dip of faults, which is difficult for us to do geological surface modeling and contour mapping with faults. This paper presents a fault-constrained interpolation algorithm, which is an effectively-improved method on fault locus algorithm.The new algorithm can effectively deal with the fault-constrained interpolation problem only with the plane position information of faults. Finally, the paper validates the algorithm by introducing a real data case.更多还原
