A Study On The Material Of Ecological Protection Slope In The High-Cold And High-Elevation Area And Its Application In The Abrupt Rock Slope

Under the influence of corrosion by rainwater and frost-melt, collapse and landslip, so far as to debris flow, occurs badly on the abrupt rock slope of high-altitude area and damages its ecological environment; and what'more, in the high-cold and high-altitude aera , the application of ecological restoration technique of the abrupt rock slope is limited and the study of ecological material is essentially placed in the blank.So it is significant to study slope protection theory,method and ecological material, which is most important and difficult technique of ecological slope protection as ecological restoration technique of the abrupt rock slope.With the guidance of foundation theory such as geotechnical engineering, garden vegetation, pedology, soil magnetism and environment engineering and the base of slope ecological protection, this paper studies ecological material protection techniques which issuitable for abrupt rock slope. According to climate and geography character in high-coldarea, by indoor trial, the paper researches the material component impact on the physical and chemical property and presents reasonable component mixture ratio of the ecological material and analyses the aggregates, drought resistance and fertilizer effect of the material.The field trial, on the k7+008～k7+063 slope of the west approach at Zhegu mount tunnelRoad 317,evaluates fully construction techniques and protection function of the ecologicalmaterial. Through the spot sampling test and the indoor emulations experiment, it has studied the relationship between the good physics, chemistry and the mechanics characteristics of the JYC ecological material and the plant of high -cold and high-altitude region to recover and grow, and further elaborated the method of study and function mechanisms. According to the need of market and requirement of construction on the scene, it has been done the detailed analysis and the application study to the commercialization of the JYC ecological material and the physical design of slope protection. In a word, there are some main achievements as following:1) It has researched and developed the JYC ecological material, and further probed into its function mechanisms and the method of ecological protection slope. Ecological material protection slope technique, which is suitable for abrupt rock slope in high-cold area, has been formed elementarily.2) Regarding JBA,YQS, and CXL fertilizer as addition agent of the ecological material, magnetic fertilizer as ecological fertilizer, the material take on character such as water holding capacity, fertilizer retaining, prime cluster structure and binding power, which realize the destination of ecological protection of the abrupt rock slope.3) The JYC ecological material belongs to the high-quality material that contents rich nutrients, and preserves moisture and fertility in the soil very strong. 4) Ecological protection technique of the abrupt rock slope in high-cold and high-altitude aera should adopt ecological material protection method. The grass seeds of ecological protection slope should choose the anti-cold, anti-infertility and extensive management cold grass seeds.5) The JYC ecological material protection slope technique can not only guarante the stable of slope and protect natural ecosystem view, but also economize the engineering expenses; and what'more, the JYC ecological material has high application value and wide marketing outlet.
