摘　　要：为探讨施工期铁路路堤边坡水土流失规律 ,对秦沈客运铁路专线一段路堤边坡进行了人工降雨试验与天然降雨实测 ,结果表明 ,路堤边坡的主要侵蚀形式是沟蚀 ,沟蚀量较面蚀量大得多 ,主要侵蚀因子是次降雨量及路堤顶面宽度。In order to investigate the behavior of soil erosion on the slope of railway embankment during construction,the experiment comparing artificial rainfall with natural rainfall on Qinhuangdao Shenyang special line of passenger trains was conducted.The results show that the main type of soil erosion is gully erosion, the amount of soil erosion caused by gully erosion is higher than that by surface erosion. The principal factor causing soil erosion on the slope is individual amount of precipitation and the width of the embankment. An empirical equation to predict soil erosion on the slope was given.
