为了探讨岩石变形过程中渗透性变化的特点，对软、硬岩进行了不同压力条件的全应力-应变过程渗透性对比试验。试验结果反映出在变形过程中不论是渗透性-应变关系特点，还是渗透性量值，软岩和硬岩均表现出明显差异。在对比分析试验所获得的应力-应变、渗透性-应变关系特点基础上，分析探讨了软、硬岩石全应力-应变过程渗透性差异的主要原因，认为岩石变形破坏过程的渗透性主要取决于变形破坏的形式和特点。

In order to investigate the behavior of permeability of rocksalong complete stress-strain path, a series of laboratory tests for both hard and soft rocks under different confining pressure,pore pressure and seepage pressure have been performed. The test results show that the permeability of hard rocks is obviously different from that of soft rocks not only in permeability-strain behavior but also in value of coefficient of permeability.Comparing the stress-strain behavior with the permeability-strain behavior during the complete deformation process of the rock obtained from tests, this paper analyses the basic mechanism causing difference in permeability behavior between hard rock and soft rock, and reveals that permeability behavior depends mainly on the fracture form and character of rock.
