A Study On The Deformation Performance Of H Type Slide-Resistant Pile

In the landslide renovations of the civil engineering such as railroad, highway etc, slide-resistant piles are widely adopted, and this kind of retaining structure is proved to work well in practice. But the calculation methods for slide-resistant pile don't go all the way. Currently, the domestic routine calculation methods for slide-resistant pile have their shortcomings to a certain extent. With the rapid development of computation technique, the force state of piles is analysed with finite element method, which offers a kind of new approach for pile's design and calculation. Finite element method can consider piles and soil as a whole, practically simulate their interaction, and offer reasonable basis for design and construction.In this paper, Yibin Wuliangye paper box factory 2~# landslide control engineering is taken as an example. Firstly, the stability of landslide is evaluated, and then the interaction of slide-resistant piles and soil is simulated with finite element software ANSYS to analyse the internal force state of h type slide-resistant pile, it is found that the outer pile of h type slide-resistant pile sustains the greater part of the internal force. In succession, the force state of h type slide-resistant pile and that of the single pile are compared, and that h type slide-resistant pile is shown to have more slide-resistant capability. Then some kinds of different distance between piles and embedment depth are chosen, the force state of h type slide-resistant pile influenced by distance between piles and embedment depth is analysed, and that optimal distance between piles is 3.2 meter and optimal embedment depth is 5.0 meter is derived, which accords with actualproject. Therefore, it is feasible to simulate the force state of slide-resistant pile with finite element software ANSYS.
