Stability Analysis of High and Steep Slope and Numerical Simulation of Anti-slip Pile Reinforcement
There are a large number of high and steep slopes in the mountainous areas along the eastern coast of China,most of which are composed of gravel silty clay and silty clay. During the Meiyu season in summer,the soil water content of the slope is high,it is relatively wet and soft,and its strength is reduced,which easily leads to landslide disasters. Anti-slip piles are widely used in slope reinforcement and treatment projects due to their good anti slip support effect,minimal disturbance to the landslide,ease of construction,and strong adaptability. Taking a landslide control project in the southeastern mountainous area as an example,the morphology and structural characteristics of potential landslide were analyzed,and anti-slip pile reinforcement measures were proposed. The reinforcement effect was analyzed using finite element software,and the deformation and destruction of the slope and anti-slip piles were analyzed. The results showed that the safety factor of the slope without anti-slip piles was 1.09,which was in an unstable state. After treatment with anti-slip piles,the safety factor of the slope was 1.44,which improved safety. The sudden change in bending moment and shear of the pile at the soil rock joint requires comprehensive consideration in design. The results can provide reference for the use of anti-slip piles in landslide control projects.
