黄土高原矿区边坡生态恢复治理研究———ＰＶＣ 板材格构锚杆梁植被种植保障技术

In order to solve the problems of poor effect of traditional engineering measures on landscape,easy failure of structure over time and unscientific selection of vegetation species,and protect the ecological environment of loess plateau mining areas,using vegetation for slope protection and erosion control to restore the slope ecology can achieve long-term and effective functions of retaining soil and protecting slope and beautifying environment. This paper presents a technique of ecological restoration and treatment of slope based on PVC plates lattice anchor beam,and discusses its structure design and construction method. The use of PVC plates instead of concrete material not only makes the structure more portable,but also improves the durability,and solves the defect of self-significant and later strength damage in the conventional use of reinforced concrete. In addition,the time effect that the PVC plates lattice anchor beam structure will gradually fail over time is considered,and the reinforcement effect of plant roots is gradually enhanced during the growth process of plantroots,until the failure of the structure completely depends on the plant roots to play the role of slope reinforcement,thus realizing the concept of dynamic management of slope stability and later reinforcement. At the same time the use of PVC plates is environmentally friendly,what harm to human health,PVC plates has better durability,from the transport cost,construction period and post-maintenance of PVC plates has more advantages. In accordance with the principles of naturalness,safety,diversity,functionality and landscape in ecology,this paper puts forward the method of ecological restoration of slope in loess plateau mining area by using vegetation community type of irrigated grass,and ecological restoration of slope engineering in loess plateau mining area by using multi-stage platform of slope supplemented by planted trees. The typical vegetation in the loess plateau mining area is sorted out,which provides a basis for the ecological restoration of slope engineering in loess plateau mining area.
