摘要
基于康滩水源地水文地质条件分析的基础上,概化含水层水力特征、垂向、侧向边界,依据水文地质概念模型建立地下水数学模型。经过水位拟合检验和水均衡验算,说明含水层结构、水文地质参数的确定、边界条件的概化等处理较为合理,所建立的地下水数学模型能够较为真实地反映研究区地下水系统的实际情况。本次模拟结果的总补给量为3.780 3万m^3/d,总排泄量为3.86万m^3/d,均衡差为-0.079 7万m^3/d。呈现微弱负均衡。
Based on the hydrogeological conditions analysis in the water source area of Kangtan,Generalization on the hydraulic characteristics,vertical and lateral boundaries of the aquifer,it is established the mathematical model of groundwater based on the hydrogeological conceptual model. Through the water level fitting test and the water balance calculation,it shows that the aquifer structure,the determination of the hydrogeological parameters and the generalization of the boundary conditions are reasonable,the groundwater mathematical model can reflect the actual situation of the groundwater system. The simulation results of the total supply of 3. 780 3 million m-3/d,the total excretion of 3. 86 million m-3/d,the balance of- 0. 079 7 million m-3/d. It presents a weak negative equilibrium.
