Model Experimental Study on the Stress Characteristics of Double Row Slide-resistant Piles for Slope Protection Under Different Pile Layout Methods
In order to study the stress characteristics of double row slide-resistant piles under different pile layout methods,model tests were conducted to analyze the changes in pile top displacement and pile body bending moment of double row slide-resistant piles under different loads.The research results show that when using the parallel layout without connecting beams and the parallel layout with connecting beams,the maximum bending moment of the front and rear row slide-resistant piles occurs in the loading section,and the maximum bending moment of the rear row slide-resistant piles is greater than that of the front row slide-resistant piles.The force on the front and rear row slide-resistant piles is uneven,indicating that the above layout method is unreasonable and not recommended.When using the parallel connected beam plum blossom pile layout method,the displacement of the top of the front and rear row slide-resistant piles during the initial deformation stage is basically the same,and under the action of landslide thrust,the force on the front and rear row slide-resistant piles is relatively balanced.It can be concluded that the parallel connected beam plum blossom pile layout method is reasonable,and it is recommended to use it.The maximum bending moment of the slide-resistant pile body in the loading section is greater than that of the embedded slide-resistant pile body.In the design of slide-resistant piles,reinforcement in the loading section can be considered.
