植被护坡工程是防治公路路域土壤侵蚀的一种措施,不同的工程措施和植被措施具有不同的防护效应。通过室内坡面径流小区模拟实验,结果表明不同工程措施、不同喷播材料初期的防护效果差别较大。文章引进USLE方程,对该方程式的评价因子进行改造,研究了丹拉高速内蒙古集老段不同工程的防护效果,结果认为第一阶段防护效果是以工程措施为主导,各种防护措施都可以减小土壤侵蚀量,不同措施间的防护效果差别明显;第二阶段植被防护为主导作用,其不同措施间防护效果都在90%以上,措施间防护效果差别不大,但是防护效果比第一阶段都有了增加。
Vegetation slope protection works is a measure to prevent and treat soil erosion in road areas. Different engineering measures and vegetation measures have different protective effects. Through the simulation experiment of indoor runoff slope runoff, the results show that the protective effect of the different seeding materials differs greatly in different engineering measures. The introduction of the USLE equation, the evaluation factor of the equation to transform, study the Danla high-speed Inner Mongolia set the old section of the protective effect of different projects, the results show that the first phase of the protective effect is dominated by engineering measures, a variety of protective measures can be reduced The difference of protective effect between different measures is obvious. The second stage of vegetation protection plays a leading role, and the protective effect among different measures is above 90%. The difference between protective measures is not significant, but the protective effect is better than that of the first stage Have increased.
