摘要
简要分析了廊道的水流特征,通过引入等效渗透系数,构建廊道取水的"渗流-管流"耦合模型,并用之于陕北佳县木头峪水源地廊道取水工程,确定了开采方案,同时计算了开采方案枯水期廊道取水的允许开采量,最终确定木头峪地下水廊道开采方式允许开采量为16 900 m3/d。建立的廊道取水数学模型能较好地反映廊道的水流特征。
Based on the analysis of the flow characteristics in the gallery,a coupled seepage and pipe flow mathematic model is developed by adapting the equivalent hydraulic conductivity.The model is used in the Mutouyu water source region to get the pumpage of the gallery and the best mining plan.The results show that in dry season,the newly added reasonable yield is 16 900 m3/d.The model can well reflect the flow characteristics of the gallery.
