摘　　要：通过现场抽水试验及工程降水监测,分析深厚黄土地下水井流规律,提出了在间歇抽水条件下黄土降水的计算模型和参数.将该模型及参数运用于建造在深厚黄土和高地下水位地基上的三原西郊水库大坝施工过程设计和计算中,结果表明,该计算模型和参数用于深井降水设计能够满足施工进度的要求.Based on field pumping tests and dewatering monitoring in engineering, the rule of well flux in deep loess areas was analyzed, and the calculation model and parameters for dewatering in loess areas were proposed under the intermittently pumping condition. The model and parameters were applied to calculation and design for the Sanyuan Xijiao Reservoir to be built on the foundation of deep loess with high water table. The result shows that the present model and parameters for dewatering design in deep wells can meet the requirement of the construction schedule.
