摘　　要：铁路工程属于建设类项目,其主体工程和临时工程施工均会扰动原地表,造成新的水土流失。以新建包满铁路(白巴段)工程为例,采用经验公式法和类比法相结合的研究方法,预测了工程建设可能带来的水土流失,并通过引入水土流失影响指数SWII对可能造成的水土流失影响程度进行了定量分析研究。结果表明,本工程建设新增水土流失总量为4.02×104t;水土流失影响指数为0.2721,低于我国铁路行业平均水平。Railway project belongs to construction project,it will disturb the original earth＇s surface during the construction of major and temporary engineerings,and then soil and water loss will be formed.Here,taking the project of Baiyunebo-Bayinhua section of Baotou-Mandoula Railway as an example,the total amount of soil and water loss is predicted,and the quantitative analysis on benefit and loss of soil and water loss is made by leading into the impact index of soil and water loss（SWII）.The result shows that the added numuber of soil and water loss is 4.02×104 tons,and the impact index value of soil erosion in this project is 0.2721,which is lower than the averaged value of impact indices of railway construction projects in China.
