Abstract: Researching on the highway compress roadbed slope rainfall erode formulas trem 7 various factors ,this pape has received a series of important results, which includes the different compressed soil erode formulas of Xi'an's, and the critically eroding gradient angles in different conditions of Xi'an's compressed soil, etc.these can be made as guidee in designing the rainfall compress roadbed slpoes .

Key words: compress roadbed slope;slope erode, man-made rainfall;critical erode gradient angle

摘要： 系统地进行了压实黄土路基边坡的7大因素变化条件下降雨冲刷试验研究,得出西安和甘肃压实黄土边坡降雨冲蚀强度经验公式、坡面最大冲刷强度的临界坡度等系列结论,对压实黄土路基坡面防护设计具有积极的指导作用.
