Numerical Analysis Of Slope's Stability That Plant Root Reinforce Slope

Since the reform and opening-up policy , the economy of our country developed rapidly, infrastructure such as highway and railway got rapid progress,and formed a lot of artificial slopes.These artificial slope mostly damaged slope's original ecological environment,and caused a lot of waste about cubic meter of earth and stone. in this case,Looking for a way that can protect slope and keep the ecological environment of the slope become a very important problem.Bioengineering techniques have been in wide use in slope protections as a branch of science and technology.Using vegetable to the slope defense and reinforcement is not only benefit to slope stability, but also to the environment protection. This method has been paid far and wide attention in recent years. But the peace of the bioengineering techniques for slope protection islagging behind the applying in engineering practice.The study of he bioengineering techniques for slope protection is still proceeding on qualitative understanding now.So it is very necessary to deliberate how the roots reinforce the slope.first through the literature research, this paper Summarizes the research results of the former,and Discusses the configuration of plant roots and its related revetment effect;Then through the theoretical derivation obtained the mechanics effect that root reinforcement anchorage traction the slope and computational models that Plant roots anchorage the slope; on that basis build the finite element model and Discusses various influencing factors that plant roots anchorage the slope,And comparison of slurry reinforced slope,find who is better.Finally summarized the how to choose the slope protection plant and the specific methods of protection and construction plan,And give the corresponding Suggestions.
