天津市宝坻区某地块水文地质调查抽水和微水试验结论探讨

Discussion on pumping and micro water test results of hydrogeological survey of a plot in Baodi, Tianjin

本文分析了场地水文地质调查中监测井1个落程的定流量抽水试验,抽水稳定时间达到8h以上,并进行水文恢复观测;通过抽水试验的开展查明工作区目的含水层地下水及变化幅度;分别计算各含水层的渗透系数等水文系数;并根据单井涌水量,评价含水层的富水性。

In this paper, the constant flow pumping test of a monitoring well in hydrogeology survey is analyzed, the pumping stability time reaches more than 8 hours, and the hydrological recovery observation is carried out. The water abundance of aquifer is evaluated according to the water inflow from single well.
