Loess Highway Slope Experimental Study On Flexible Protection Technology

With the question of the survival and development of the continuous deepening of awareness, people's awareness of the gradual strengthening of the ecological environment, the state has been attached great importance to highway construction and environmental protection of the ecological environment, if we do not consider the road construction and the coordinated development of ecological environment, not only in human and economic losses experienced, but also seriously affect the roads after the completion of the normal operation of the environment at the same time devastating, slope protection technology is a flexible protection and plant protection works the organic integration of a new type of protection method, which make full use of protective works Deep solid reinforcement and plant shallow slope of the characteristics of environmental protection and ecological construction and environmental protection to achieve and take into account the purpose of ecological restoration, and now soft slope protection technology has become a highway of a trend of slope protection, slope protection represents direction of development.In this paper, the main highway from the Gansu loess slope region type and mechanism of disease, the level of Gansu Province Ping(liang)～Ding (xi) Highway loess slope protection works as the background, through the rain erosion test at the scene contrast without protection, plant fiber protection, vegetation protection board that the protective effect in three ways geocell combined with rain erosion protection of indoor experiment was conducted to study the impact of rain erosion protective factors and three forms of the role of slope stability on the degree of plant fiber slope, vegetation geocell board and flexible protection of these three forms of reinforcement mechanism, the corresponding design and construction process, through the finite element numerical analysis shows that the flexible protection technology for highway slope in loess area of governance and protection the role of the way at the same time flexible protection technology for the analysis of economic benefits for the loess areas of disease prevention and treatment of road slope to provide a theoretical basis for loess region by drawing on the road slope protection.
