| 摘 要： | 抗滑桩由于其桩位布置灵活、施工比较方便、治理效果可靠,是滑坡治理工程中广泛采用的一种抗滑措施。一直以来抗滑桩设计都是沿用手工查表计算的方法,采用这种传统的抗滑桩设计方法不仅增加了工程师繁重的计算工作,而且很难实现优化设计。文章在对抗滑桩的工作机理进行分析的基础上,讨论了影响抗滑桩经济性的主要因素,以抗滑桩的截面宽、高和长度为基本要素,建立了抗滑桩优化设计的数学模型,并采用遗传算法进行求解。最后对一个工程实例用传统设计方法和优化设计方法所得的结果进行了比较,结果表明,对抗滑桩进行优化设计不仅能减轻工程设计人员的工作量,还可以在满足安全的条件下明显的降低工程费用,在滑坡治理工程中具有一定的实际意义。

| Abstract: | Anti-sliding piles have been widely used in slope control engineering due to their effectivity and convenience.The traditional method to design anti-sliding piles is to calculate by hand and it will be a hard work for engineers to design anti-sliding piles with this method.Furthermore,it is difficult to optimize the design of anti-sliding piles.In this paper,based on the analysis of the mechanism of the anti-sliding piles,the main factors which influence the cost of the anti-sliding piles,such as the section size and length of the anti-sliding piles,are discussed.A model with these factors is established for the optimization of the anti-sliding piles and is solved through genetic algorithm.The outputs of an example with the two methods are compared.It turns out that we can release the designer and decrease the cost of the anti-sliding pile. |
