摘　　要：基于新疆生产建设兵团第6师北塔山牧场大石头洼地区的自然地理、气象、水文、水资源、地下水补给、径流、排泄等水文地质条件,从大石头洼地地形地貌、储水空间、地下水的赋存与分布规律和圈闭性角度,对大石头地下水库成库条件的可行性进行论证研究,并在考虑区域水文特征条件下,选取库区面积为23.5 km2,对地下水库的库容进行分析计算,研究结果表明:大石头洼地地下水库边界几近于封闭,内部地下水径流条件比较好,赋水体砂卵砾石层具有一定厚度,地下水位埋藏较深,储水空间充足,在下游末端小沟出口处,含水层较薄,渗透性一般,成库条件很好,非常适宜修建无坝地下水库;大石头地下水库最小库容理论值为1234×10^(4)m^(3),最大库容理论值为2115×10^(4)m^(3),调蓄库容理论值为881×10^(4)m^(3)。大石头地下水库未来作为北塔山牧场重要的供水水源地对区域供水保障及水资源合理配置具有重要意义。Based on the Xinjiang production and construction corps sixth division north hill ranch rock depressions in physical geography,meteorology,hydrology,water resources,groundwater recharge,runoff,discharge and other hydrogeological conditions,from the rock depressions landform,water space,the occurrence and distribution of groundwater and trap Angle,the feasibility of underground reservoir rock into library condition demonstration research,and under the condition of considering the regional hydrological characteristics,the selection of the reservoir area of 23.5 km2,analyze the underground reservoir capacity calculation,The results show that the rock nearly closed depressions underground reservoir boundaries,the internal conditions of groundwater runoff is better,water sand gravel layer with certain thickness,buried depth of ground water level is relatively great,the storage space is enough,the small groove in the end of the downstream outlet,with thin aquifer,the permeability,into library condition is very good,very suitable for building without closing the reservoir;The theoretical minimum and maximum storage capacity of large rock underground reservoir are 1234×10^(4)m^(3),2115×10^(4)m^(3) and 881×10^(4)m^(3) respectively.As an important water supply source of Beitai mountain Ranch in the future,big stone underground reservoir will be of great significance to regional water supply guarantee and rational allocation of water resources.
