| Abstract: | As a cost-effective and environmentally compatible way to protect slopes, live staking has been widely used in west countries. This paper introduces the application and installation of live staking. Then its reinforcement mechanism is discussed. Moreover, the elasticplastic finite element method is used to analyze the stability of slopes reinforced by live staking. Based on the discussion of some factors such as the length, location, amount, inclination and roots of the live staking, many useful rules are obtained. |
