摘要
通过对潜水含水层中的非完整井基坑涌水量计算方法的分析 ,探讨引入抽水“有效带”的概念 ,将非完整井群涌水量计算转化为等效完整井群涌水量计算方法的可行性及由此产生的相对误差大小。通过几个实例计算表明 ,简化方法一般可将基坑涌水量计算误差控制在 2 0 %以内 。
Based on analyzing the discharge of the partially penetrated wells in phreatic aquifer,introducing the conception of 'the effective zone'of pumping,probing into the feasibility and comparative error by translating the calculation of the discharge of the partially penetrated wells into the calculation of the discharge of the equivalent completely penetrated wells.Several examples indicate that simplified method can control the comparative error of the discharge of one pit within 20percent,then prove that the simplified method to a certainly has practical value.
