摘　　要：在黄土地区,植被恢复很慢,由于黄土本身的特性以及突发性的暴雨,对路堤边坡的冲蚀作用十分明显,甚至造成路基的坍塌。用格室防护黄土路堤边坡的冲刷试验研究,目前尚未见报道。通过一系列对比试验并详尽分析,发现土工格室对黄土路堤边坡冲刷防护的效果明显。在此基础上,对土工格室的冲刷防护机理进行了初步探讨。Erosion of the road embankment caused by rainstorm, is very serious in loess zone, even leading to road embankment collapse. There has rarely reported about the anti-eroding effects of geotexiles on road embankment so far. Based on detailed analysis on results of a series comparing test on anti-eroding effect of geocells, a conclusion is drawn that the using geocells is an effective way to improve road embankment's anti-eroding ability. Finally, the anti-eroding mechanism of geocells is discussed.
