摘　　要：通过对某铀矿尾渣库地质条件的分析 ,运用一维水流动的二维弥散方程来对该尾渣库地下水中2 3 8U和2 2 6Ra核素运移进行了长达 10 0 0a的模拟。模拟给出了污染范围 ,对具有类似条件的尾渣库模拟计算亦有一定的参考价值。Based on local geological conditions of the uranium tailing impoundment of an uranium mine,a 2D dispersion equation of 1D water movement was used for model transport of 238U and 226Ra in groundwater around the uranium tailing impoundment of an uranium mine in 1 000 years,the ingredient was suitable to insite leaching of uranium,the result showed polluted area.It proved that the mo del could be taken as reference for the similar.
