摘　　要：结合某赤泥堆放场的水文地质条件,通过模拟试验,探讨了赤泥及冲灰水中氟化物进入地下水的运移规律。结果表明,赤泥堆场在大气降水和冲灰水的浸溶、淋溶作用下,氟化物会大量溶出,并随赤泥废液一起下渗,新鲜赤泥及石灰岩碎石对氟化物有一定的吸附作用,但吸附能力有限。The hydrogeological conditions of a red mud yard were simulated to discuss the migration law of fluoride from red mud and ash water to ground water.As indicated by the results,a large quantity of fluorine would dissolve out from the red mud yard soaked and leached in rainwater and ash water,and then infiltrated with the red mud waste,fresh red mud and limestone could adsorb fluorine,but the adsorption capacity was limited.
