针对黄土地区公路边坡受降雨侵蚀破坏较为频繁的情况，将降雨侵蚀灾害作为一个单独的灾种，阐述黄土边坡降雨侵蚀破坏机理。降雨侵蚀破坏的偶然成分很少，边坡抗灾能力受到威胁的程度需要提前预测，使工程提前采取相应措施。研究建立黄土地区公路边坡降雨侵蚀灾害易损性的评价方法和评价流程，采用侵蚀模数作为评价指标，通过分析USLE水土流失方程中各因子的取值和计算方法，计算某黄土地区的侵蚀模数，根据易损性等级的划分分析出边坡受降雨侵蚀的易损性和抗灾能力，发出预警信息，以便及时采取预防措施，减少和控制灾害的发生。

In view of the situation that the highway slope of loess area is frequently damaged by rainfall e -rosion ,the paper took rainfall erosion as a separate disaster species and expounded the destroy mechanics of rainfall erosion on loess slope .The accidental elements of destroy of rainfall erosion is very few .The degree of slope disaster threatened need to be predicted in advance so as to to take measures for project in advance .The paper researched to set up the evaluation method and evaluation procedure of rainfall ero-sion disaster vulnerability on highway slope of loess area and took erosion modulus as evaluation indexes . Through the analysis of value of each factor and calculation method in USLE equation of soil and water loss.It computered a erosion modulus of loess region .According to the level of vulnerability ,the paper analyzed the vulnerability of rainfall erosion on slope and the ability of anti-disaster .It is necessary that on the premise of prediction and early warning information to take corresponding preventive measures and to reduce and control the occurrence of disaster .
