| 摘 要： | 通过分析均质含水层中的割离井渗流模型的井的出水量公式，引进相应的理论曲线（井流函数）。该函数是一个仅与相对井径有关的函数。分析割离井法的井流函数的性质发现，井流函数可以简化，从而将雅各布直线图解法引入割离井法中反求水文地质参数；其步骤与常用雅各布直线图解法步骤相似；最后用实例验证该方法的可行性。

| 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) have been introduced.These functions are only related to the relative diameter of the well.By getting the simple the discharge formulas,the linear graphic method is introduced into the method of isolated-well to conversely calculate the hydrogeology parameters.The procedures are similar to the linear graphic method.The feasibility of the method is verified at the end of the paper. |
