【摘要】 路基边坡防护是防止路基病害、保证路基稳定、改善道路环境景观、保护生态平衡的重要措施。目前基于生态防护的黄土路基边坡防护形式研究还较少。因此合理设计边坡的坡型,根据边坡的水文地质条件和坡型正确的选择植被类型对于边坡的稳定性和生态系统的恢复至关重要。本论文首先详细调查了河南、陕西及山西等黄土地区高速公路路基边坡防护设计方法、施工工艺、应用效果等技术资料。根据资料发现,黄土路基边坡病害可划分为以下三种类型：坡面雨水冲刷侵蚀破坏、坡体失稳滑坡、侵蚀—失稳破坏；总结出了黄土路基边坡防护现状和难点。本论文在郑西客运专线详细地质勘察资料的基础上,选取两段代表性的黄土路段进行详细的边坡稳定性分析及坡型与支护设计；然后考虑植物防护,研究黄土边坡的浅层稳定性。最后根据对黄土边坡植物生长状况的现场调研,从利于坡面植物生长、快速起到防护作用的角度考虑,建议黄土边坡的坡比不宜陡于1：1；再结合对比各种坡型边坡稳定性分析结果,最终得出黄土路基边坡在该段坡型的最优方案。根据对黄土边坡破坏模式、防护现状的调研,黄土边坡稳定性的分析研究成果,归纳郑西客运专线郑西客运专线渑灵段黄土边坡防护方法的选择,并通过现场试验总结出了郑西客运专线渑灵段黄土边坡植物配置的适宜模式。更多还原

【Abstract】 The protection of the slope is an important measure to prevent diseases of the slop, guarantee the stability of slop, improve the environment landscape, and protect the ecological balance. At the present, in the form of loess subgrade slope protection has not too many studys based on the ecological protection. So the reasonable to design slope type, according to the hydrogeology conditions and slope type to select the right type of vegetation for the stability of the slope and ecosystem restoration is very important.At first, this thesis detailed investigations He Nan, Shan Xi and Shan Xi province as well as other loess highway areas, covering the protection of the slope design methods, Construction technology, applying effects and other technical data. According to the information, the loess slope disease can be divided into three types: Erosion damage at the face of the slop by rain, landslides of slop instability, the damage of erosion-losing stability.Summary the cosplay and difficulty of the protective of the loess slop.This thesis in ZhengZhou to Xi’An passenger line detailed on the basis of geological exploration, Select two representative types of the slope to stability analysis, subgrade and protection type design. According to the research of loess slope plant grow, from beneficial for plant growth and quickly to provide protection, suggest the slope ratio of the loess slopes not steeplier than 1:1; Then contrast the results of the numerical analysis software, finally get the optimal subgrade of loess slope section.According to the destruction mode research, cosplay protection, and stability analysis of the loess slope, sum up the choose of the protection of the Mian Ling of Zhen Zhou to Xi’An passenger line, and according to field trial, sum up the plant proportion of loess slop of the Mian Ling of Zhen Zhou to Xi’An passenger line.更多还原
