摘要

利用伺服试验机对灰岩和砂岩进行了应力应变全过程渗透性试验，研究了岩样变形和破坏过程中的轴向应变与渗透率之间的关系，分析了岩样环向应变对渗透率的影响规律，探讨了岩样变形破坏前后渗透压差随时间的变化关系。结果表明，岩样渗透率与应力状态密切相关，渗透率的峰值滞后或超前于应力应变峰值，这与岩石介质本身的特性有关；渗透率-环向应变曲线与渗透率-轴向应变曲线有相同的变化趋势，但岩石环向变形比轴向变形更能灵敏地反映渗透率的演化规律；岩样变形破坏峰值前后的渗透压差与时间均遵循负指数关系。最后对岩石变形破坏过程中的渗透机理作了讨论。

Abstract

Permeable experiments on complete stress-strain course of limestone and sandstone were carried out in servo-controlled testing machine. The relation between axial strain and permeability of rock specimen during the course of deformation and failure is made by a detailed investigation. The effect law of lateral strain on the permeability of rock specimen is analyzed. At the same time

the variance relation of permeable pressure head with time before and after the deformation and failure of rock specimen is also discussed. The result shows that the permeability of rock specimen is closely related with the stress state; and the peak value of permeability comes out nearby the peak value of stress-strain

which has a close relation with the property of rock material. There are the same variance tendency between permeability-lateral strain curve and permeability-axial strain curve. However

the lateral deformation of rock can reflect more sensitively the evolution law of permeability than the axial deformation. The permeable pressure head complies with negative exponential relation with time during the course of deformation and failure of rock specimen. In the end

the permeable mechanism is made with a detailed discussion during the course of deformation and failure of rock specimen.
