摘　　要：针对PSO算法的实用性和优化效果,选用四个测试函数,计算它们在不同的PSO优化算法和不同维数下的结果,并给出边坡稳定性平价实例计算。计算结果表明不同的PSO优化算法的实用性和效果不同,同种PSO算法对不同问题的优化效果也不同,随着维数的增加各个优化算法的效果也越来越差。In view of practicability and optimization effect of PSO algorithm, four test functions were selected to calculate their result in different PSO optimization algorithms and different dimensions, and the calculation of slope stability evaluation example was given. The calculation result shows that the practicability and effect of different PSO optimization algorithm are different, and the optimization effect of different problems with the same PSO algorithm is different, the effects of all optimization algorithms also get worse with the increase of dimension.
