| 摘 要： | 为了解西北某中低放废物处置场裂隙岩体的渗透性及其优势方向,对裂隙几何参数进行了统计分析,划分出优势裂隙组,再通过概率分析,取得优势裂隙的几何参数,并将其代入渗透张量计算程序中进行计算,得到岩体的渗透张量计算值;最后对渗透张量计算值进行分析,并根据前期抽水试验得到的渗透系数对裂隙岩体渗透张量进行修正,取得合理有效的渗透系...

| Abstract: | In order to know the permeability of fractured rock and dominant strike of fractures at a certain low-medium radioactive waste disposal site,the statistical analysis of fracture's geometrical parameters are accomplished.Based on this,the dominant attitudes of fractures are determined.Then,the dominant geometrical parameters are obtained by the probable analysis.According to the geometrical parameters,permeability tensor can be calculated with a specially developed computer program.Finally,by analyzing the p... |
