复合含水层在平原地区分布较普遍，该含水系统在垂向上的物质交换包括越流和对流两种方式，本文根据质量守恒原理，以稳定流为基础，提出了上部弱透水层一下部含水层模型的定解问题并给出了相应的解；对双层含水层提出了一个判别地下水流主要运动方向的计算公式，并结合实例进行了计算，该方法将为复合含水层中污染组份沿垂向和径向的分布提供详细的计算方法。本文的计算模式均以两层含水层为例，对于实际各种含水层组合。均可以采用上述办法建立模型并给出相应问题的解。
The composite aquifer is widely distributed in the plains. The material exchange in the vertical direction of the aquifer includes two modes of over-flow and convection. Based on the principle of mass conservation and based on the steady flow, an aquifer of the upper aquitard The solution of the model is given and the corresponding solutions are given. A formula to determine the main movement direction of groundwater flow is proposed for double aquifer, and the calculation is made on the basis of practical examples. The vertical and radial distributions provide detailed calculations. In this paper, the calculation model is based on two aquifers, for the actual combination of aquifers. We can use the above method to establish the model and give the solution of the corresponding problem.
