To study the different permeability characteristics of rock, transient permeability tests of limestone and diorite were carried out. The permeability evolution and the relation between pore pressure and time of rock specimens during the complete stress-strain course were investigated. The strain-permeability equations of rock specimens during the deformation and failure course were set up. Finally, the penetration mechanism of two types of rocks was analyzed.

为研究岩石不同渗透特性，对石灰岩和闪长岩进行了瞬态渗透实验，研究了岩样全应力－应变过程中的渗透率演化规律以及孔隙压差与时间的关系，并建立了岩样变形破坏过程的应变－渗透率方程，最后分析了这两种不同类型岩石渗透机理。

The result shows that the phenomenon of the sudden jump of permeability occurs at the peak strength and keeps very low unchanged permeability before the peak strength for diorite. But limestone's permeability gradually increases with increasing deformation before and after the peak strength.

实验结果表明，闪长岩的渗透率在峰前很低且基本不变，在峰值强度时产生"突跳"现象，石灰岩的渗透率在岩石强度峰值前后随岩石变形逐渐增大。
