| 摘 要： | 借助变异函数的优点，即能够反映区域化变量张开度的空间变化相关性和随机性特征,利用Kriging方法对单裂隙中张开度进行估值，由交叉验证法的拟合结果认为估值结果较为合理，并且通过溶质运移试验验证了Kriging法对单裂隙张开度的估值是可行的。

| Abstract: | Based on the advantage of variogram that can indicate the characteristic of aperture for relativity and randomicity of space change, Kriging is used to estimate aperture of single fissure. It is shown that the result is reasonable through cross validation. The experiment of solute transport on single fissure shows that it is reliable using Kriging to estimate of aperture for single fissure. So it is feasible for the means of stochastic simulation to compute aperture. |
