以哈尔滨至同江高速公路为研究对象,布设简易径流小区,测定公路路基边坡在不同防护措施作用下的径流量、土壤侵蚀量,分析不同防护措施的水土保持效果。结果表明,路基边坡工程+植物的综合防护措施对防止土壤侵蚀有显著的作用,就水土保持效果来说,应优先采用工程+植物的综合防护形式;在采取植物防护措施时,可采用灌草结合的方式。
Taking Harbin-Tongjiang Expressway as the research object, a simple run-off plot was set up to measure the runoff and soil erosion of the roadbed under different protective measures, and the soil and water conservation effects of different protective measures were analyzed. The results showed that the comprehensive protection measures of subgrade slope engineering + plants had a significant effect on preventing soil erosion. For the effect of soil and water conservation, the comprehensive protection form of engineering + plants should be given priority. When adopting plant protection measures, The way grass is combined.
