少陵塬黄土潜水层深井降水计算模型及应用

Dewatering Calculation Model of Deep Well-pumping in Phreatic Water of Loess in Shaolingyuan and It's Application

根据现场抽水试验所表现出的水流运动规律,提出少陵塬隧洞降水计算模型和参数确定方法,将计算结果和试验结果进行了比较,结果表明此公式合理可靠,应用于少陵塬隧洞降水工程中,取得了良好效果。此计算模型结构简单,应用方便,可供其它黄土地区类似降水工程参考。

On the basis of flows law in pumping experiment,dewatering calculation model and the method of parameters settlement in the model are advanced . The comparison between the calculated results and experimental data shows that the model is feasible. Good results are achieved in using it into Shaolingyuan tunnel. The Calculation model is simple and convenient, and it can be referenced by the similar dewatering projects in loess region.
