摘要煤矸石路基中存在以汞为主的多种微量污染元素。依托某高速公路已燃煤矸石路基,采用室内试验和数值分析,基于多孔介质溶质运移动力学理论,建立了煤矸石路基-汞-土体-大气降水-地下水多孔介质数学模型,研究了煤矸石路基中汞元素的扩散规律。结果表明:已燃煤矸石路基溶液pH值与物质组分有关,与降雨等外界环境无关;不同pH值条件下,煤矸石溶液pH值对汞释放量影响较大,对汞释放速率影响较小,初始pH值越低,汞元素的释放量越大;随着时间的推移,煤矸石路基中汞元素向周边土体和地下水有效扩散,在18年后达到生活饮用水卫生标准,如继续扩散,将严重影响周边环境。本研究旨在为煤矸石路基环境评估与治理提供一定的理论支撑和借鉴。

Abstract: There are many kinds of trace pollution elements, mainly mercury, in the road base of coal gangue. Based on the theory of solute transport mechanics in porous media, a mathematical model of coal gangue roadbed mercury soil atmospheric precipitation groundwater porous media was established to study the diffusion rule of mercury in coal gangue roadbed. The results show that: the pH value of coal gangue subgrade solution is related to the material composition, and has nothing to do with the external environment such as rainfall; under different pH values, the pH value of coal gangue solution has a greater impact on the release of mercury, but has little impact on the release rate of mercury. The lower the initial pH value, the higher the release of mercury; with the time of atmospheric rainfall, the mercury element in coal gangue subgrade is released to the surrounding soil mass and the effective diffusion of groundwater, in 18 years to meet the sanitary standards of drinking water, if continue to spread, will seriously affect the surrounding environment. It can provide a theoretical support and reference for the environmental assessment and treatment of coal gangue subgrade.
