| Anti-slide piles which are an effective measure for controlling the landslide have an important position in treating the landslide in all countries of the world. But for long time some problems existing in anti-slide piles design process can't be resolved entirely all the time, such as how to establish the location of piles, how to establish the distance between the piles by calculation and so on. Based on other researchers' a series of study products, the author studied that the treatise starts from the history and application of anti-slide piles, at the same time ,discuss roundly the interaction mechanism between landslide and anti-slide piles as well as the method of design and calcuation.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 an ti-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 machanim 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 plasticd eformationt heory 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. |
