摘要
在分析晋城市延河泉域地质、水文地质条件的基础上,建立了泉域岩溶地下水的概念模型和数学模型,采用基于迦辽金(Galerkin)有限单元法的AQUA3D软件对泉域岩溶地下水资源进行数值模拟研究。通过模型识别与检验,将岩溶地下水位数值模拟计算值与实测值较好地拟合,表明所建模型是合理和有效的,可以用于实际。据此用所建模型计算了两个降水方案条件下的泉域岩溶地下水可开采资源量,最终确定可开采资源量为6.26 m3/s.研究结果可为泉域岩溶地下水开发利用和保护提供科学依据。
Based on the analysis of the geological and hydrogeological conditions in Yanhe spring basin of Jincheng city, the conceptual model and mathematical model of karst groundwater were presented, and the numerical simulation of karst groundwater was carried out by using AQUA3D software base on Galerkin finite element method. From model identification and verification, the groundwater level calculation results were well fit with measured values, proving the model＇s rationality and effectiveness. The model was used to calculate the allowable exploitation quantity of karst groundwater at two precipitation schemes. At last, the allowable exploitation quantity was ensured as 6.26 m^3/s. The results would give scientific foundation to the exploita- tion and protection of karst groundwater.
