钻孔单位涌水量换算的探讨

Discussion of Conversion about Borehole's Specific Capacity

针对目前利用钻孔单位涌水量评价含水层富水性所存在的问题,较详细地总结了利用3次降深抽水试验资料进行单位涌水量换算的方法,并通过工程实例深入地分析了为什么要进行单位涌水量换算,在此基础上提出了对只有1次或2次降深抽水试验数据的处理,以使单位涌水量换算和含水层富水性评价工作更加完善。

Towards the question about using borehole＇s specific capacity to assess the water rich property of aquifer,we summarize the method about using pumping test data of three times drawdown to convert specific capacity in detail and analyse why to convert specific capacity through example of engineering in depth.On this basis,we present how to deal with the pumping test data of one or two times drawdown.The conversion of specific capacity and assessing about water rich property of aquifer will be more completed.
