为揭示新型植被板护坡的防护机理,验证其实际防护效果,运用工程水文学原理对新型植被板护坡的防护机理进行了研究分析,通过现场小规模冲刷试验对新型植被板护坡的防护效果进行验证。通过对植被板护坡坡面产流机理分析,分别给出了蓄满产流和超渗产流的产流条件和相应的计算方法。在理论分析和现场试验的基础上得出结论:植被板护坡对降雨具有显著的调节和再分配作用;新型植被板护坡结构合理,能有效降低坡面水流含沙量,且施工简便,能尽快恢复路域环境,是一种良好的新型边坡防护体系。
In order to reveal the protective mechanism of the new vegetation plate slope protection and verify the actual protective effect, the protective mechanism of the new vegetation plate slope protection is studied by the engineering hydrology principle. The protective effect of the new vegetation plate slope protection is verified by the on-site small-scale erosion test . Through the analysis of the mechanism of runoff on vegetation slope, the runoff conditions and corresponding calculation methods of runoff and supersaturation flow are given respectively. Based on the theoretical analysis and field experiments, the conclusion is drawn that vegetation slope revetment has significant regulation and redistribution effect on rainfall; the new type of vegetation slope protection structure is reasonable, which can effectively reduce sediment flow in slope surface, and the construction is simple and can be done as soon as possible To restore the road environment, is a good new slope protection system.
