【摘要】 地下水时空分布及污染质运移一般都建立在较为简单的地形地质条件下,对于断裂带等较为复杂的地质结构一般很少单独考虑其地质构造的影响。为此建立了华北平原内禹王山断裂带附近某化工区水文地质概化模型,对比区域内断裂带在不同源汇性质下对地下水流场以及溶质运移的影响。研究表明,断裂带力学成因性质及断层岩性会影响断层的导水性能,张性断裂带呈导水性,采用导水率对断裂带进行模拟计算具有更好的拟合性;断层上盘与下盘岩性越相似,模拟情况与实际拟合程度越良好。本研究成果对断裂带附近的地下水环境保护研究及地下水污染防控具有重要借鉴意义。更多还原

【Abstract】 The spatial and temporal distribution of groundwater and the transportation of contaminants are generally based on relatively simple topographic and geological conditions. With little consideration given to specifically complex geological structures,geological generalization methods are generally adopted for complex geological structures such as fault zones. In order to cope with this issue,a generally hydrogeological model is established in a chemical area near Yuwang Mountain fault zone in Plain of North China,comparing the influence of the fracture zone in groundwater flow field and soluting transport between different source and sink properties,and studies further on the influence of leakage from the chemical area to surrounding residential and farming areas. According to the analysis,the difference of mechanical genesis and lithology of faults will lead to the difference of water conductivity of faults. If the tensional fracture zone is water-conductivity,the hydraulic conductivity should be used to calculate and simulate the fracture zone. The more similar the lithology of the upper and lower plate of the fault is,the better the simulation and the actual fitting degree are. The results of this study have important reference for the study of groundwater environmental protection near the fault zone and the prevention of groundwater pollution control.更多还原
