通过野外调查和对几个代表性的碳酸岩露头的实际裂隙测量 ,得到了山西柳林泉区岩溶含水岩组中的裂隙分布规律 .在此基础上建立了反映泉区实际情况的三维可混溶溶质运移模型 .模型用于描述柳林泉区地下水中Cl- 的运移行为 ,模拟效果良好 :模型拟合阶段水头和Cl- 浓度的计算值与观测值误差绝对值的平均值分别为 0 .36m、6.5mg/L ;模型检验阶段水头和Cl- 浓度的计算值与观测值误差绝对值的平均值分别为 0 .4 9m、6.3mg/L .所有结果显示两者基本一致 ,说明所建模型是可靠的 ,可以用于实际 .据此用所建模型预报了柳林泉区柳林电厂水源地投入使用后咸水入侵的可能性 .
Through field investigation and actual fracture measurement of several representative carbonate outcrops, the distribution of fractures in the karst aquifer group of Liulin Spring Area in Shanxi Province was obtained. Based on this, the three-dimensional miscibility The model is used to describe the migration of Cl- in the groundwater of Liulin Spring District, and the simulation results are good: the average of the absolute value of the error of the head and the Cl-concentration in the model fitting stage is 0 respectively. 36m, 6.5mg / L; the average value of the absolute value of the error between the calculated value of the head and the Cl-concentration at the model test stage was 0.49m and 6.3mg / L, respectively. All the results showed that the two were basically the same, The model is reliable and can be used in practice.Accordingly, the model is used to predict the possibility of saltwater intrusion after the water source of Liulin Power Plant in Liulin Springs District was put into operation.
