摘要
通过对单裂隙试件进行的渗透性实验，提出了考虑岩石物性参数的渗透系数表达式，并根据实验结果建立了在有效应力作用下裂隙闭合量Δｂ与渗透系数ｋｆ和有效应力σｃ的关系式。这对深入研究裂隙渗流，简化有限元计算，解决工程实际问题具有一定的指导意义。
On the basis of the experimental study on fluid percolation through single fractures,the paper brings forward the permeable formula which takes the characteristic coefficient into account.It also sets up the relationship between fracture displacement Δ b and effective stress σ e ,and permeable coefficient k f .It is important to study the fracture fluid,in solving engineering problems and simplifying the calculation of FEM.
