本文通过对某工程带观测井的抽水试验数据的分析与比较,并根据边界条件的不同,选择适用的公式,较准确地得出符合实际的渗透系数,对该类型的抽水试验结果的分析,及渗透系数公式的正确选择提供了较好的例证,为基坑降水的设计更细化、更合理。
Based on the analysis and comparison of pumping test data of an observation well with an engineering project and the selection of applicable formulas according to the different boundary conditions, the actual permeability coefficient is obtained accurately and the pumping test results of this type are analyzed. And the correct choice of permeability coefficient formula provides a good example of the design of foundation pit precipitation more detailed and more reasonable.
