摘要
白垩系基岩孔隙裂隙承压含水层为研究区地下水主要含水层之一,水文地质模型概化为各项异性非均质。根据地下水系统运动规律及分布特征建立三维非稳定流数学模型,采用广义差分法对其求解,并以长春市区为例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;为研究区地下水系统可持续管理提供了科学理论依据。
Confined pore and fissure aquifer in Cretaceous bedrock is one of the main aquifers in Changchun area and the hydrogeological conceptural model can be simplified as anisotropy and heterogeneity. According to the movement＇s feature of groundwater system, the mathematic model of three-dimensional transient flow is assumed and generalized difference method is used to solve the flow equations and the groundwater flow model has Been calibrated and verified. The model simulation result is in accordance to the actual hydrogeologie condition and the eaculated water table is consistent to the monitored water table. The results can provide a scientific theoretical foundation for sustainable management of groundwater resources in the study area.
