| 摘 要： | 考虑水文地质参数在时空上有较强的变异性，运用正交多项式方法确定渗透系数的二次漂移式，进而确定出渗透系数剩余R（x）的变差函数γR（h），运用泛克立格法对渗透系数变异程度值进行了验证，结果表明非列线数据运用克立格法计算是符合工程要求的。

| Abstract: | Considering high temporal and spatial vaiation of the hydrogeologic parameters, using the orthogonal polynomial approach determined the second order drift formula for permeability coefficient, then calculated the variable function γR（ h ） of the R （ x ） , and using the Universal Kriging approach, analyzed spatial variable number of permeability coefficient. After take identification, analyzing results is satisfactory with engineering need. |
