基于有限元法的傍河水源地地下水资源评价及预测
|
摘要
某电厂傍河水源地已运行30余年。近年来,由于周边地下水水位下降比较严峻,已影响到电厂正常的生产用水。通过对水源地前期的勘查资料、历史水位长观资料及本次的水文地质勘查,对水源地水文地质条件进行再分析,概化评价区内含水层水力特征、边界条件,依据水文地质概念模型建立地下水数学模型。经过流场和水位拟合检验,模型用于该水源地水资源评价与预测。模拟结果显示,该水源地呈现负均衡。通过对拟合后的模型,预测电厂不同开采情况下,水资源的趋势变化,为电厂用水提供了决策依据。
The water source of a power plant has been in operation for more than 30 years. In recent years, due to the severe water level of the surrounding groundwater, the normal production water of the plant has been affected. The hydrogeological condition of the water source is analyzed by means of the exploration data of the water source, the historical water level and the hydrogeological exploration. Generalization on the hydraulic characteristics, boundaries of the aquifer, it is established the mathematical model of groundwater based on the hydrogeological conceptual model. Through the flow field and the water level fitting test, The simulation results presents a negative equilibrium. By using the fitted model, the trend of water resources under different mining conditions is predicted, which provided a basis for decision-making on the use of water in power plants.
