摘要
随着城市地下空间开发的深入,超大超深基坑的不断出现,地下水的处理对基坑安全的作用越来越明显,需要对降水设计及应用进行更加深入的研究,文章通过对某工程带观测井的抽水试验数据的分析与比较,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,对以后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。
With the deepening of the urban underground space development and the emergence of super ultra deep foundation pit, the functions of groundwater treatment on foundation pit safety are becoming more and more obvious, so it needs to take more research on precipitation designs and applications. In this oaoer, theactual coefficient of permeability accurately was data about a project with observation well and ing applicable formula. And it provides a good meability coefficient formula corrected selection drawn through the analysis and comparison of pumping test according to the different choices of boundary condition choos example for this type of pumping test result analysis and per in the future.
