| 摘 要： | 开发建设项目引起水土流失的评价是目前研究的热点之一。采取抽样调查法和侵蚀断面测量法，对陕西北部山丘区公路开挖边坡侵蚀进行了定量分析。在选择和确定原始开挖面的基础上，分段测量了开挖边坡长度、高度和侵蚀沟深度等特征值，并结合边坡开挖时间计算出边坡年均侵蚀深度。通过分析研究各县区不同地貌单元面积，在假定县内道路分布均一的情况下，计算了各县区侵蚀参数和区域道路开挖边坡的年侵蚀量。研究结果表明，该区年均道路开挖边坡侵蚀剧烈，每年侵蚀量约达510710t。

| Abstract: | The evaluation of erosion induced by construction is one of research hot points presently. The erosion of cutting-slope of highway in north Shaanxi Province is investigated and evaluated by measuring the erosion depth on slope surface through 43 sampling sites. Based on the original cutting slope, the length of cutting slope of highway, the height of slope and channel depth of erosion on slope are measured section by section. The annual average erosion depth is calculated with time of cutting slope and total erosion depth. Based on the composition of landform of each country, and an assuming of that the distribution of highway is similar, the erosion parameter and cutting slope erosion are analyzed. The research shows that the erosion of cutting-slope of hightway is intensive, the annual erosion weight accunts for 510 710 t. 3 tabs, 1 fig, 6 refs. |
