摘要
简述了地下水数值模拟计算的基本理论与求解方法,运用Modflow软件,建立了青铜峡某水源区地下水开采的数学模型.对模型参数、源汇项处理进行了分析确定,使模型具有较好的模拟仿真度.对该地下水开采区进行了20 a地下水位变化的模拟预测,给出了不同时期研究区地下水运动特征及水位(降深)分布.计算数据分析表明5 a地下水补给、排泄在年内保持均衡,地下水位基本稳定,同时探讨了利用Modflow地下水计算成果进一步预测水位下降引起的地面沉降问题.
The theory and solving method of groundwater simulation have been introduced briefly.The groundwater mining mathematical model of a water source area in Qingtongxia region has been set up.The authors analyze and determine the parameters and source-sink term in the model,which taken the model to be verified very well.The forecasting simulation of groundwater change in the area has been made for 20 years future besed on modflow software,in which moving properties of seepage and groundwater level distribution are given in the area,during different periods.By analyzing simulation data,it is showed that the dynamic balance between supplement and drainage in the area can be achieved after 5 years,groundwater level also steadied,Further forecasting settlement induced by decrease in water level,has been discussed based on achievements in simulation of Modflow.
