Abstract
In order to investigate the behavior of soil erosion on the slope of the highway embankment during construction,the experiment with natural rainfall on Xichang-Panzhihua highway was conducted.The results show that the main type of soil erosion is gully erosion,and the amount of soil erosion caused by gully erosion is higher than that by surface erosion.The principal factors causing soil erosion on the slope are individual amount of precipitation,the width of the embankment and soil erodibility.There are good linear relationship between the amount of soil erosion and the principal factor,and their correlation coefficient is 0.9985~0.9989.A model to predict soil erosion on the slope is given in the paper.
