| 摘 要： | 泉水作为济南市的城市名片，具有重要的经济和社会价值，把握泉域内突发污染质泄漏对其产生的影响至关重要。本文概化建立了济南市的水文地质概念模型，利用地下水非稳定流数值模型对济南市区泉群附近范围的地下水进行了分析研究，得到了济南市区泉域内地下水的时空分布规律及污染物运移特性。在此基础上，分析某新建项目污染质泄漏对地下水环境产生的影响，通过设置不同的横纵向弥散度对污染物运移特性进行探究。结果表明，在泉群附近区域内，污染物纵向运移过程中对流起主要作用，纵向弥散度的取值影响较小； 而污染物横向运移过程中弥散起主要作用，横向弥散度的取值影响较大。本研究成果对泉群附近的地下水环境保护及地下水污染防控具有重要借鉴意义。

| Abstract: | As the symbols of Jinan city, the springs are essentially valuable for the citys economy and society. It is important to follow the influence of sudden sewage leakage. This paper conceptualizes the concept model of hydrogeology. It studies the temporal and spatial distribution of groundwater and the features of contaminant transportation using the building transient groundwater flow model. On this basis, the effect of a new built project to the groundwater environment is researched. The features of the contaminant transportation are investigated by setting different longitudinal and transverse dispersities. The result shows that the advection plays a leading role in the longitudinal transportation of contaminants in the area near the spring groups. But it is exactly the opposite in the transverse direction. The research result has the model significance to the groundwater environment conservation and the groundwater pollution control. |
