中文摘要：
应用地质统计方法研究渗透系数场的空间变异性。利用MMR含水层场地实测数据,通过去类分析、特异值处理、正态变换,逐步逼近研究区渗透系数的稳健变差函数,得到三维渗透系数场的几何各向异性套合模型。在此基础上,采用普通克里格法和指示克里格法、高斯序列模拟法和指示序列模拟法分别对数据进行插值和条件模拟。最后结合具体的地质条件,对四种方法在渗透系数场生成中的应用进行对比分析和评价。
英文摘要：
Based on Geostatistical Software Library （GSLIB）, the spatial variability of the hydraulic conductivity fields is examined by using the Kriging and conditional simulation of geostatistics, from which the standardized exponential model fits the test data got from the aquifer in MMR. Cell declustering, dealting with the outliers and normal score transformation, are used because they provide robust variograms. Then we get geometric anisotropy nested structure in 3D to the test data. Further, we adopt ordinary Kriging, indicator Kriging, sequential Gaussian simulation and sequential indicator simulation separately to interpolation and conditional simulation. Finally, the results are statistically analyzed and estimated with the specific geological conditions.
