【摘要】 在四坪山建造极低放射性核废物填埋场,建填废物紧临洪积扇。查明洪积扇地下水的演化特征,可为核废物的安全填埋提供依据。使用地球化学软件PHREEQCI,进行洪积扇地下水的反向地球化学模拟,推测地下水在径流过程中发生的水-岩作用,并计算发生水-岩作用的矿物相的量。更多还原

【Abstract】 As good understanding of evolution features of groundwater will be the scientific basis for safe disposal of nuclear wastes,the paper makes a case study of a very low level radioactive wastes disposal project which designs to dump radioactive wastes into a landfill which besides alluvial fan.By using PHREEOCI software,the paper makes a inverse geochemical modeling of groundwater in alluvial fan to make the water-rock interaction in run-off process clear and calculate the amount of mineral facies in water-rock interaction.更多还原
