| 摘 要： | 为探讨高速公路施工期路堤边坡水土流失规律,对西昌-攀枝花高速公路路堤边坡进行了天然降雨条件下水土流失观测试验,结果表明,路堤边坡的主要侵蚀形式是沟蚀,主要侵蚀因子是次降雨量、路堤顶面宽度及土壤可蚀性,土壤侵蚀量与次半宽雨量之间存在着良好的相关关系,其相关系数为0.9985～0.9989.提出了预测西昌-攀枝花高速公路路堤边坡土壤侵蚀量的土壤侵蚀模型.

| Abstract: | In order to during construction, investigate the behavior of soil erosion on the slope of the highway embankment 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. |
