前言富平地下水库属河谷型水库,位于渭河北岸支流石川河中游段。河谷嵌于黄土原中,地势开阔平坦,含水层分布稳定,厚度大,储水能力强;周边为透水性较弱的黄土所围;80米左右以下为相对隔水的粘土、亚粘土层。若以地下水开采前全河谷区平均水位埋深12.41米计,到目前开采地下水已腾空的库容达4.0亿立米以上。因此,如果有 Foreword Fuping underground reservoir is a valley reservoir, located in the middle reaches of the Ishikawa River tributary Ishikawa. Valley embedded in the loess original, flat and open topography, aquifer stable distribution, thickness, water storage capacity; surrounded by weak permeability loess surrounded; 80 meters below the relatively water-retaining clay, sub-clay layer. If the underground water area before the exploitation of the entire valley of the average water depth of 12.41 meters, to the exploitation of groundwater has been vacated capacity of 400 million cubic meters or more. So, if there is
