The Research Of Anti-slide Pile For Landslide Cure

Anti-sliding pile has been used for prevention and cure landslide more than forty years. The treatise starts from the history and application of anti-slide pile,and discuss roundly the interaction mechanism between landslide and anti-slide pile as well as the method of design and calculation.Meanwhile,the author summarizes certain rules and puts forward some opinions for the design,such as the method in the treatise of design with its characters.Based on a successful design for strengthing of landslide of anti-flood wall base located at Wuhu Huajing bridge,the author analyzes the result of landslide and the bug of the last design which was a failure,and build the simplified machanics model of anti-slide piles. From the model,the landslide thrust and remanent sliding resistance behind the piles can be calculated with the limit equilibrium theory and coefficient of transmission method. The internal force of the anti-slide pile is calculated with the cantilever pile method, the frame on elastic base method and Tomio Ito's plastic deformation theory on the base of the reasonable parameter. With the comparison of the theoretic result and the fractual measure result,the author analyzes the error's reason. Finally,it have been pointed out that the factors which were not considered and the limition of calculation method.
