摘要
在分析太原盆地松散沉积层水文地质条件及钻孔资料(343个)的基础上,确立盆地地下水三维流动特征,建立太原盆地松散沉积层的地质结构模型、地下水的三维流动数学模型,应用数值模拟方法再现了太原盆地地下水流动的时空变化规律。结果表明,太原盆地地下水多年平均补给量在8亿m3左右,近10年每年平均超采量在0.8亿m3左右。
By analyzing the hydrogeological conditions of the loose sediment and boring data （343 bores） in Taiyuan Basin, a geological structural model and a 3D groundwater flow mathematical model based on the flow characteristics were established. The models successfully reproduced the dynamic processes of groundwater flow during the simulation period. The results show that the annual average water resource recharge is about 800 million m^3, and about 80 million m^3 of groundwater have been overexploited every year for the last ten years in Taiyuan Basin.
