本文所讨论的是在越补含水层中,不考虑弱透水层贮存水的释放时,地下水以定流量流向完整井的非稳定流理论解。越补含水层用非稳定流抽水试验求解含水层参数的基本方法是标准曲线对比法,此种方法在实用中往往具有较大的任意性,所求得的参数难于准确。另外,可用拐点法求解,但此种方法要求抽水试验出现稳定的降深(即最大水位降深),这需要较长的抽水 This paper discusses the unsteady flow theory of groundwater flowing to a full well at a constant flow rate in a recharge aquifer, irrespective of the release of reservoir water in the aquitard. The more the aquifer is replaced by the unsteady flow pumping test, the basic method for solving the aquifer parameters is the standard curve comparison method. This method often has greater arbitrariness in practice, and the obtained parameters are difficult to be accurate. In addition, the inflection point method can be used to solve this method, but this method requires a steady decline in the pumping test (that is, the maximum water level drop), which requires a longer pumping
