| 摘要: |
| 分析了无上、下补给,井内定水位且初始水位呈水平时,均质含水层中割离井渗流模型的出水量公式,引进了仅与相对井径有关的井流函数,通过井流函数性质的研究,将试算法引入割离井法反求水文地质参数,其步骤与常用泰斯试算法的步骤相似。最后用实例进行验证,其结果与目前已有的方法相近。 |

| Abstract: |
| By analyzing and simplifying the isolated-well discharge formulas with water level in the well fixed and the homogeneous isotropic aquifer having no recharge from up and down,the curves of this type,only related to the relative diameter of the well,have been figured.The method of trial and error has been inserted to the method of isolated-well to inversely calculate the hydrogeology parameters by researching into the property of the well-function.The steps are similar to the algorithm of Theis.In the end,verified by examples,the results resemble those of the other methods. |
