发布时间：2018-11-06 12:42
【摘要】：随着我国西部大开发的推进,山区交通建设蓬勃发展,基建过程中产生大量次生裸地,水土流失现象严重。大片裸露岩质边坡不但带来了安全隐患,而且因其颜色灰暗、单调对生态环境产生视觉污染,与我国生态文明建设理念相违背。如何快速恢复裸露的岩质边坡的生态并稳固边坡不仅是公路景观设计的一大难题,也是山区道路行车安全的保障。基于对国内外边坡生态恢复技术相关文献的检索分析,提出了一种快速高效自适应公路高陡岩质边坡生态恢复技术(已获国家专利授权),并给出了该技术的详细参数、工作原理及关键施工工艺。该技术解决了高陡岩质边坡固土难、根系缺水、绿化见效慢、绿化期短暂、施工难度大、成本高、后期需人工浇水等问题,与现有技术相比优势明显。该生态恢复技术将植被的生长和岩体的特征结合起来发挥优势,不但可提高绿植存活率,还能稳固边坡。本研究成果弥补了现有边坡生态恢复技术的不足,更适合于公路高陡岩质边坡的生态恢复。
[Abstract]:With the development of China's western region, the traffic construction in mountainous area is booming, a large number of secondary bare land is produced in the process of capital construction, and the phenomenon of soil and water loss is serious. Large areas of bare rock slope not only bring safety hidden danger, but also because of its dark color, monotonous visual pollution to the ecological environment, which is contrary to the concept of ecological civilization construction in China. How to quickly restore the ecology of exposed rock slope and stabilize the slope is not only a difficult problem of highway landscape design, but also a guarantee of driving safety of mountain road. Based on the retrieval and analysis of the related literatures of slope ecological restoration technology at home and abroad, a fast and efficient adaptive highway ecological restoration technology for high steep rock slope (authorized by the state patent) is proposed, and the detailed parameters of the technology are given. Working principle and key construction technology. This technique solves the problems of high steep rock slope, such as difficult to fix soil, water shortage of root system, slow effect of greening, short period of greening, high difficulty of construction, high cost, need artificial watering in the later period, and has obvious advantages compared with the existing technology. The ecological restoration technology combines the growth of vegetation with the characteristics of rock mass, which can not only improve the survival rate of green plants, but also stabilize the slope. The research results make up for the deficiency of the existing slope ecological restoration technology and are more suitable for the ecological restoration of highway high steep rock slope.
