摘要
研究区地下水主要为玄武岩类孔洞裂隙水,水文地质模型概化为各向异性非均质,根据第四系玄武岩承压含水层中地下水的分布特征及流动规律,建立二维非稳定流数学模型,采用广义差分法对其求解.通过研究区井群对模型进行识别、验证.结果表明,计算模型与实际水文地质条件比较接近;计算水位与实测水位相吻合.为城市地下水可持续性管理提供科学理论依据.
The study area groundwater is mainly holes fracture water, Hydrogeological model summarized as anisotropic heterogeneous, According to the distribution of groundwater characteristics and flow pattern in the Quaternary basalt confined aquifer, then establish two-dimensional unsteady flow mathematical model, and use generalized difference method to solve it. Through the model in the study area identified and validated by the wells. The results show the calculation model pretty close to the actual hydrogeological conditions. Calculation of water levels consist with measured water level. This study provided scientific theoretical basis for the sustainable management of urban groundwater.
