所考虑的问题是通过使用压实粘土衬里来减少水库的失水。假设垂直流动,得到了非均匀土中稳态饱和和非饱和流动方程的解。给出了覆盖式水库水头与渗流损失的关系。分析了被困在毯层下面的空气压力大于大气压力的影响以及粘土膨胀的重要影响。为了减少膨胀,还考虑了在毛毯上放置透水层的影响。考虑到采用弹性压实技术,可降低储层的渗透率和渗透率。在垂直方向上,在自然和非自然条件下,对自然和非自然条件下的平衡方程进行求解。在此基础上,推导出了一种关系,即地层与储层之间的关系。分析了空气压力对空气质量的影响。
Synopsis The problem considered is that of reduction of water losses from reservoirs by use of a lining of compacted clay. Vertical flow is assumed, and solutions of the equation for steady-state saturated and unsaturated flow through non-homogeneous soil are obtained. These give the relation between head of water in the blanketed reservoir and seepage loss. The effect of air pressure, greater than atmospheric, of the air trapped below the blanket and the important effect of swelling of the clay are analysed. The effect of a pervious overlayer placed on the blanket in order to reduce swelling is also considered. On considere l'emploi d'une couverture d'argile compactee afin de reduire les pertes par infiltration dans les reservoirs. En supposant l'ecoulement vertical, on obtient des solutions de l'equation d'ecoulement permanent en milieu sature et nonsature. On en deduit une relation entre les pertes et la hauteur de l'eau dans le reservoir. On analyse aussi l'effet de la pression de l'air, superieure a ...
