| 摘 要： | 本文介绍了在低压下(最大压力20MPa)对完整岩石和含自然裂面岩石渗透率的实验研究。在实验中对四种材料(花岗岩、变质岩、大理岩、水泥块)用六种方法进行了测试。实验结果表明,低压下完整岩石的渗透率为1μd量级,含裂面岩石的渗透率为1md量级,渗透率明显地与应力状态和加载方式有关。

| Abstract: | This paper deals with laboratory investigation into Permeability of intact rock, natural facture rock under lower pressure (maximum test pressure is 20MPa). Four materials (granite, metamorphic rock, marble and cement block) have been tested in experiment by using six kinds of ways. Tile results show that permeability of intact rock under lower pressure is of 0.001 md magnitude and fractural rock is of 1 md magnitude, and rock permeability is clearly related to stress state and loading way. |
