摘    要:通过岩石三轴压缩渗透试验,揭示了岩石在全应力应变过程中的渗透规律,发现岩石渗透率一般不是常数,而是随应力应变过程中岩石内部结构演化特征改变,岩石渗透峰值多发生在岩石破坏后的应变软件阶段,因此,防止岩石破坏与控制岩石破坏后变形的进一步发展,对于预防岩层突水事故是同等重要的。

关 键 词:全应力应变  渗透规律  应变软化  岩石三轴压缩渗透试验  渗透率  岩土工程

Abstract:By means of permeating tests of rock under triaxial compression, the permeability rule in full strain-stress process has been studied. It is found that the permeability coefficient is generally not a constant, but varies with the inner structure evolution of rock in fill sttess-stfain process. The highest permeability oc- curs mostly in strain softening period. The results indicate the importance of both controlling fracture occur- rence and deformation development after rock failure in prevention of water in-rush catastrophe.
Keywords:full stress-strain  permeability rule  strain softening
