【摘要】 本文根据泰安东武傍河水源地水文地质勘测资料,借助于地下水系统数值模拟软件包——Aqua3D,建立了水源地地下水水流和溶质运移模型,通过观测井实测水位资料率定了水文地质参数,进行模拟校正,所得拟合曲线显示建模的水位变化趋势和实测的水位变化趋势基本一致,拟合程度较高;选择两种不同开采方案,应用模型模拟,预测结果显示:主供水区承压岩溶水亚硝酸盐浓度满足城市饮用水供水要求,但水源地潜水及大汶口镇承压水水质受河流污染影响较大,对饮用水供水安全构成威胁。更多还原

【Abstract】 This articlebased on geohydrological exploration data in source of drinking wellfields nearby river in Dongwu of Taian,with the helpof Aqua3D which is softwareused in numericalsimulation of groundwater,built the source’s model of groundwater current and solute moving.Made sure source’s geohydrological constant by mensurating the water level in exploration logging,proofreaderthe parameter accordingsimulation,then we got the fitting curve and the water level mutative trend revealedby the modelingwas consistent basicallywith the metrical numerical value,they have great coherence.We chose two different exploitationprojects and simulated by modeling,the forecast showed: the nitrite concentration in artesian karstic water can satisfy the request of city’s drinking water,but the quality of phreatic flow in headwater and artesian aquifer in Dawenkou town would have been polluted badly becauseof the pollution of the river,that will intimidate the safety of drinking water.更多还原
