摘要
基于地下水动力学理论,建立了唐山市古冶区地下水数学模型,并对模型参数及边界条件进行确定。通过模拟得到研究区域内全年地下水变化情况及其流场分布,其中水位变差及地下水流向与当地实际相符,说明该模型合理、可靠。同时计算得到研究区域内近年地下水补排量,将其与储变量比较可知,在近年取排水条件下,地下水供给难以满足当地取水需求。对此,在不同径流量保证率下,提出相应的建议采水方案,以保证唐山市古冶区地下水取水需求。
Based on the characteristics of the groundwater system in Guye District of Tangshan City, a mathematical model was developed, and the model parameters and groundwater boundary conditions were discussed. The model was used to verify the year-round groundwater level changes and the groundwater flow fields. The results were closed to the field observations, which indicated that the model was reasonable and reliable. The recharge and discharge amount of groundwater in Guye District were also calculated. The results showed that the groundwater storage in the Guye District had failed to meet the water requirements in the area in recent years. Water extraction schemes under different guarantee rates of runoff were proposed to solve the problem.
