摘要
通过对岩样渗透试验数据回归得到岩样的渗透特性 (非Darcy流因子 β ,非线性指数n ,渗透系数K)与轴向应变的关系 ,并将多块岩样渗透特性的回归值进行统计 。
In this paper, the index of penetrating property of rock is the non-Darcy factor, β; the nonlinear power, n; and the hydraulic conductting coefficient, K. On the basis of penetrating test of a group of rock specimen , (1)the penetrating property of rock specimen in fixed axial strain is obtained by nonlinear regression, and (2)the relation between the penetrating property of rock specimen and its axial strain is obtained by linear regression, and (3)the penetrating property of rock is described by the statistic index, i.e. ,the average value and standard difference, is obtained by the penetrating property of the group of rock specimen.
