摘　　要：根据大量物理勘探数据,采用FEFLOW软件建立地下水数值模拟模型,用以确定模拟区稳定可靠的开采强度。开展不同开采强度条件下的逐日数值模拟,预测地下水降深,分析水源地在开采条件下对水文情势、其他用水户等方面的影响。从连续10 a地下水数值模拟情况看,地下水水源地在开采强度为2.60万m^(3)/d的条件下,地下水处于动态平衡中,不会导致水位持续下降。水源井最大降深3 m,降深为0.2 m漏斗区最大扩展面积约0.67 km2。研究成果可为冀北山区地下水水源地的建设提供科学依据和技术支持。Based on a large number of physical exploration data,FEFLOW software is used to establish a numerical simulation model of groundwater to determine the stable and reliable exploitation intensity in the simulation area.Daily numerical simulations under different exploitation intensities were carried out to predict the depth of groundwater and analyze the impact of water sources on the hydrological situation and other water users under exploitation conditions.According to the numerical simulation of groundwater for 10 consecutive years,the groundwater source is in dynamic equilibrium under the condition of exploitation intensity of 26,000 m^(3)/d,which will not lead to the continuous decline of water level.The maximum depth of the water source well is 3m,the depth is 0.2 meters,and the maximum expansion area of the funnel area is about 0.67 Square kilometers.The research results can provide scientific basis and technical support for the construction of groundwater sources in the mountainous areas of northern Hebei.
