岩石渗透性 流体(通常指地下水和石油)在动力作用下在岩石中的流动称为岩石渗流,岩石被流体渗过的性能称为岩石的渗透性。 岩石渗流对岩石力学性质有重要的影响,它会改变岩石的受力情况,引起岩石变形、破裂、软化、泥化或溶蚀,从而危及岩体的稳定性。因此岩石渗透性是岩石力学的主要研究内容之一。 渗透性基本规律 水在岩石中的渗流是一个很复杂的问题,至今还没完全研究清楚。工程上为了便于探讨,往往把水在岩石中的流动假定为同在其他边界条件下的流动一样,分为层流和非层流,并借用水力学和流体力学的原理和方法进行研究。在层流动动中,水头损失与流速呈线性关系,是1852年法国H.-P.-G.达西用砂土作实验得出的。实验用的砂土具有均匀分布的互相连通的孔隙,即所谓连续多孔介质。通过试验,得出被称为达西渗流定律的下述公式: v =KJ或
