中文摘要：

为了在不同放在的斜坡上调查土壤侵蚀的行为，出现在建设期间，有自然降雨 onXichang-Panzhihua 高速公路的实验被进行，确定流量和土壤损失。结果显示出那：(1 ) 土壤侵蚀的 mam 类型是溪谷侵蚀，溪谷侵蚀引起的土壤侵蚀的数量由表面侵蚀比那高。(2 ) 在堤的斜坡上引起土壤侵蚀的主要因素是降水，堤的宽度和雨紧张的单个数量。(3 ) 在切的斜坡上引起土壤侵蚀的主要因素是降水，切的斜坡的宽度和雨紧张的单个数量。(4 ) 在倾倒的土壤区域的斜坡上引起土壤侵蚀的主要因素是降水，扁平的房顶的宽度和雨紧张的单个数量。在土壤侵蚀和主要因素的数量之间有很好线性的关系，并且他们的关联系数是 0.935 7-0.999 8。

英文摘要：

In order to investigate the behavior of soil erosion on the slope of the different underlaying surface during construction, the experiment with natural rainfall on Xichang-Panzhihua highway was conducted, to quantify the runoff and soil loss. The results show that. （1） 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. （2） The principal factor causing soil erosion on the slope of the embankment is individual amount of precipitation, the width of the embankment and rain intensity. （3） The principal factor causing soil erosion on the cutting slope is individual amount of precipitation, the width of the cutting slope and rain intensity. （4） The principal factor causing soil erosion on the slope of the dumped soil area is individual amount of precipitation, the width of the flat roof and rain intensity. There are well linear relationships between the amount of soil erosion and the principal factor, and their correlation coefficient are 0.935 7-0.999 8.
