摘要: 在岩石抽水-注水试验的基础上,通过应力和渗透系数的关系,用数值模拟的方法讨论了应力与渗流的过程。研究结果表明,随着应力场的调整介质的渗透性将发生改变,从而对渗流过程产生影响,这种影响是非线性的,渗流作用的存在使得水位的变化与介质的渗透性的变化不是对应的关系。

Abstract: Basedon the experiment of drainage-injection and the relation of stress and osmosis parameter, the authors studied the stress and seepage process by using the numer-ical method. The result shows that the adjustment of stress field will change the osmosis of rocks and affect the seepage process. The effect is nonlinear. In other words, due to the seepage effect, the change of water level does not correspond to the change of osmosis.

Key words: Underground water, Seepage, Numerical method, Body stress, Water-level anomaly
