| 摘 要： | 在分析各种随机场离散方法优缺点的基础上,提出用泛克立格方法对渗透系数随机场进行离散.编制了KRING.FOR程序对渗透系数随机场的离散效果进行了验证,结果表明在实测点所包围区域内部用最小二乘法所求解得到的权系数而进行的克立格估值计算是符合工程要求的.并针对程序调试过程中及计算结果分析中所出现的问题,提出了相应的解决对策.

| Abstract: | On the basis of analyzing the advantages and disadvantages of various random field discretion methods,it is put forward that Universal Kringing method is applied to the discretion of permeability coefficient random field.The effectiveness of the discretion method is validated by KRING.FOR program.It is proved that the Kringing estimators obtained by least square method in the domain surrounded by measuring points can meet engineering requirements.The solution approaches to the problems found in the debugging of the program and the analysis of the computation results are presented. |
