黄土由于其独特的物质组成和结构,很容易被冲蚀。长期以来,对黄土边坡抗冲蚀防护方面有很多学者做了大量的研究和尝试,但结合黄土本身特性方面防护方式尝试的少。笔者在结合黄土本身特性的基础上提出做草泥喷护的方法,并针对有无草泥喷护的边坡做了冲刷降雨对比试验,结果表明,该方法效果良好。在冲刷最初时,有无草泥喷护边坡抗冲刷效果差不多,但是20m in后,开始出现分异,有草泥喷护的边坡效果比较明显,冲蚀量明显减少,也没有出现像没有防护边坡那样明显的细沟破坏。
Loess is easily eroded due to its unique material composition and structure. For a long time, many scholars have done a lot of researches and attempts on erosion prevention of loess slopes, but few attempts have been made in the field of loess protection. Based on the characteristics of loess itself, the author put forward the method of grass spray and compared it with the experiment of scouring and rainfall for the slope with or without grass spray. The result shows that the method is effective. At the beginning of scouring, there is almost no effect on the scouring effect of the grass-sprayed slope, but after 20m in, the divergence began to occur. The effect of slope with grass-spray was obvious and the erosion amount was obviously decreased. There is no obvious vandalism as there is no protective slope.
