| 中文摘要: |
| 以锦屏水电站坝址区右岸岩体的渗透性为实例，引入变异函数的孔穴效应模型，就渗透性的各向异性特点应用该模型的套合结构对单位吸水率的空间结构进行了分析。在此基础上，采用指示克立格(Kriging)方法对研究区域参数的渗透性进行估值计算。通过交叉验证法证实了孔穴效应模型在此研究范围的适用性，同时，这一方法的估计方差较小表明了Kriging方法它在确定裂隙介质中渗透性参数方面的可行性。 |
| 英文摘要: |
| The cave effect model of variogram is introduced and combination structure of the cave effect model is applied to analyze the spatial structure of the conductive property in the right bank of the dam in Jinping Hydro Power Project. Based on the analysis, indicator Kringing method is applied to estimate the filtration parameters in the given area. The suitability of the cave effect model is verified by cross-validation confirmation. The variance of estimation is relatively small. |
