Mechanism Of Anti-slide Pile And Its Structural Optimization

Landslide is a very common natural disasters, human engineering activities, the construction of dams, underground excavation, reservoir storage and other slope instability leading to an important reason, after years of engineering practice and theoretical research, prevention and treatment of landslide has very great achievements, particularly the rapid development of anti-slide structure applications.Anti-slide Piles is widely used in the control of landslide and slope stability. However, the design theory of computation piles are not yet ripe,the traditional design theory has many assumptions in varying degrees to avoided the comprehensive analysis of the interaction of anti-slide Piles and soil.The existing single pile are straight, did not consider the combined of single pile and the natural characteristics of the soil,when the landslide thrust is large, often with larger piles cross-section, to increased the resistance of piles.So the existing piles are thick,large and high cost. therefore, rational design of pile structure, cost-effective prevention and treatment of landslide is very important.In this paper, the following aspects were studyed with engineering examples:(1) The traditional Calculation method of Anti-slide piles;(2) Prestressed anchor Anti-slide piles'stabilizing mechanism and calculation method;(3) The Application of small Anti-sliding steel pile and its mechanism analysis;(4) The Application of hollow Anti-slide piles and its superiority;(5) Utility model invention--- the mechanism of T-based Anti-slide piles and its calculation method.
