Analysis of Hydrogeological Conditions for the Formation of Underground Reservoir in Wenquan Country,Xinjiang
The Bortala River basin in Xinjiang is short of water resources and is unevenly distributed in time and space,The water use process does not match the incoming water process,The construction of underground reservoir is of great significance to the optimal allocation of water resources.The underground reservoir in Wenquan County,Xinjiang was comprehensively analyzed from different aspects:hydrogeological condition,water source and water quality,water stor-age conditions,water replenishment conditions,water intake conditions,and ecological environment conditions.The ba-sic conditions for the construction of the underground reservoir in Wenquan County were basically clarified.The re-charge and water intake methods of the underground reservoir are preliminarily discussed.It is concluded that the aver-age daily recharge amount is 41.64 × 104 m3,the minimum area of the required infiltration canal is 11.90 × 104 m2,and the annual artificial recharge amount is 4 837× 104 m3.The self-flowing water intake project of underground water collection corridor is adopted as the water intake method.The length of the corridor under different aquifer thicknesses is calculat-ed by using the stable water inflow model of the tunnel,and a reasonable layout method of the replenishment project is proposed,which provides the design basis for the construction of the underground reservoir.
