摘　　要：大多数干旱区内陆河流山前凹陷带含有巨厚的砂砾石含水层,地下水径流条件十分优越,是一个天然的地下水库。地表水通过河道和冲洪积扇渗漏补给地下水库,在冲洪积扇下缘进入平原区后,土层颗粒逐渐变细,形成一道天然的地下阻水坝,地下径流在此受阻后以泉水的形式溢出。在分析研究坎儿井主要技术特点的基础上,结合河流冲洪积扇地形地貌特征、储水构造以及水资源转化特点,提出了建设山前凹陷带"横坎儿井式"地下水库具体设想。In arid regions,most piedmont depression areas of inland rivers containing thick sand,gravel aquifers and superior conditions for groundwater runoff,can be regarded as natural underground reservoirs,which are supplied by rivers and leakage from alluvial and diluvial fan.After through the fan,the groundwater runoff is overflowing as a spring in the plain terrain,where the particle is becoming finer and like a natural dam.By analysis of the characteristics of karezs,terrain and geomorphology of the fan,and water storage structure and transforming of water resource,this paper puts forward to a plan of building underground reservoir with cross-karez-style in piedmont depression area.
