琼北自流盆地地下水三维数值模拟研究

考虑琼北自流盆地承压水存在复杂天窗、越流补给的径流途径,将该区地下水系统刻画为完整的三维数学模型,并以雷琼坳陷盆地中心--琼州海峡中心作为承压水海底等效隔水边界,较好地解决了琼北自流盆地地下水资源模拟的承压水海底等效边界的界定,其模拟结果与水文长观孔的资料拟合度较高,表明建立的水文地质模型具有准确性,可用于地下水资源的定量评价,对合理利用地下水有重要的意义.

Three-dimension Numerical Simulation of Groundwater in Qiongbei Artesian Basin

Taking the groundwater system of Qiongbei artesian basin as the there-dimension mathematical model and the center of Qiongzhuo Strait as the equivalent boundary,this paper solves the problem of identifying the seabed equivalent boundary for the simulated groundwater resource of the basin.The results have the high coincidence with the data from the long-term observation drilling locations of hydrology.This shows that the hydro-geological model has the accuracy,can be used for the quantitative assessment of g...
