Application Analysis of Anti-Slide Pile in Hydraulic Engineering Slope Support
In recent years,h-type anti-slide pile is widely used in slope treatment engineering.Combined with the actual slope engineering,using numerical simulation techniques,a model of slope treatment with h-shaped anti-slide piles with different coupling stiffness is established,the stiffness of h-shaped anti-slide pile coupling beam for anti-slide pile body displacement,internal force and slope treatment effect is studied.The results show that ①Different range of coupling stiffness,the influence on the top displacement of h-type anti-slide pile is different.②Stiffness change of coupling beam,the influence on the maximum shear force of the back row pile of h-type anti-slide pile is greater than that of the front row pile,and the influence on the maximum bending moment of front and back row piles is different.③Take all factors into consideration,the optimum stiffness of the coupling beam is 1.5EI,the maximum displacement of the slope is only 8mm,73.3%lower than the natural working condition.The research results can provide reference for similar projects.
