在抽水条件下水位随空间和时间变化的预测,依赖于潜水层的透水率和给水度的准确测定。如何利用抽水试验资料求这两种参数也是一个关键。这种相辅相成的关系是有效地开发利用地下水资源的前提。潜水井不稳定渗流的计算是复杂的,过去为了避免繁琐的数学处理,大多近似求解,一般均假设这种渗流场的垂直分量可以忽略不计,即只考 Prediction of water level changes with space and time under pumping conditions depends on accurate determination of water permeability and feedwater level of the submersible aquifer. How to use the pumping test data to obtain these two parameters is also a key. This complementary relationship is a prerequisite for the effective exploitation and utilization of groundwater resources. The calculation of unsteady seepage flow in a submersible well is complicated. In the past, in order to avoid complicated mathematical processing, most of the approximate solutions were used in the past. Generally speaking, the vertical component of the seepage field is negligible.
