The Application Of Anti-slide Pile Optimization Design In The Landslide Treatment

As a kind of retaining structure,anti-slide pile has many advantages and has been widely used in the practice of landslide control engineering.Unfortunately,due to the subjective influence of the designers,the traditional design method of anti-slide pile can only provide a wordable solution,which is not the necessarily optimal solution.There is no doubt that an unreasonable design would bring a enormous waste.In order to find a solution to the problem of traditional design method of arduous task,inefficiency and vulnerable to subjective factors,this paper,in the practical engineering background of JiaoShuwa landslide,uses Particle Swarm Optimization(PSO)algorithm and the bat algorithm(BA),which are programmed in Matlab,to achieve the optimal parameters of the anti-slide pile.That is to say,optimal design method is used to determine the optimization of the structure.This paper,based on JiaoShuwa landslide engineering treatment,analyzes the engineering geologic conditions,structure and deformation character of the landslide,discusses the its stability,and calculates the landslide thrust.The basic theory of the design of anti-slide piles is summarized,and the internal force,displacement and reinforcement calculation of anti-slide piles are analyzed systematically.In order to bring matrix calculation of Matlab superiority into full play,the theory of matrix analysis of anti-slide pile is studied,and the internal force calculation and reinforcement of anti-slide piles are compiled on Matlab platform.Based on Particle Swarm Optimization and Bat Algorithm,the paper takes the construction cost as the optimize objective,under the conditions of ensuring the satisfy of the construction project,and builds optimization model of the anti-slide pile based on Particle Swarm Optimization and the Bat Algorithm,makes this two kinds of intelligent optimization algorithm into Matlab program,and obtain the best layout of the lowest cost.In the end,this paper assesses the optimization effect of anti-slide piles,including the internal force and displacement of anti-slide pile before and after the optimization,and the economic benefit of the optimization.Checked by analysis software GEO5 for the optimization of anti-slide pile,result shows that the optimization,compared to the original plan cost is reduced by 15%~16%,with the prerequisite of ensuring project's safety.The economic benefit is remarkable,and Swarm Intelligence Algorithm can be efficiently applied to optimization of anti-slide piles.
