| 摘 要： | 针对砂性土堤防坡面抗雨水冲刷能力弱的工程实际,建立砂性土坡面冲刷试验模型,开展降雨冲刷试验,研究不同砂性土堤防坡面保护层抗冲刷性能。分析降雨条件下不同砂性土堤防坡面保护层的冲刷过程,总结出沙土、膨润土与秸秆三者混合形成的坡面保护层能够抵抗雨水冲刷、保障植物种子顺利成长,便于施工。

| Abstract: | For the sand embankment water loss and soil erosion prevention situation,a model of sand soil surface anti erosion test was established to carry out rainfall scouring test. Based on the model test,anti-washout performance of different sand embankment slope protection layer was studied and erosion process of protection layer was analyzed. It is concluded that the mixture of sandy soil,bentonite and straw can resist rain erosion,ensure the smooth growth of plant seeds and facilitate construction. |

| Keywords: | sandy soil slope simulated rainfall scouring test sand-bentonite mixture |
