| 摘 要： | 通过分析初始水位呈水平及抽水过程中井内定水位且上部和下部无流量补给时,均质含水层中割离井渗流模型的井的出水量公式,引进仅与相对井径有关的井流函数,对出水量公式两边取对数,将流量—时间配线法引入割离井法中反求水文地质参数;其步骤与常用泰斯流量—时间配线法的步骤相似;最后用实例验证了该方法的可行性。

| Abstract: | By analyzing the discharge formulas of the seeping of isolated well among the homogeneous isotropic aquifer when the water level at the beginning is in horizontal and fixed state and no water is supplied from up and down of the well,relevant theoretical curves (well flow-functions) related only to the relative diameter of the well have been introduced.By getting the logarithm of the discharge formulas,the flow rate-time method is introduced into the method of isolated-well to conversely calculate the hydrogeology parameters.The procedures are similar to thesis flow rate-time method.The feasibility of the method is verified at the end of the paper. |
