Abstract

Abstract: The application of particle swarm optimization algorithm ( PSO) is discussed，and the parameter identification of Chongqing Ganxigou No． 1 cable-stayed bridge with the shock absorber of cables is carried out，which is based on the PSO algorithm． As was discovered by this research，once the frequency of multiple-order vibration is known，cable indexes calculated by PSO algorithm such as T，EI，K and εL are reliable．

Key words: particle swarm optimization algorithm, attached damper, parametric identification, cable-stayed bridge

摘要： 讨论了粒子群算法( PSO) 的应用，并基于PSO 算法结合重庆干溪沟1 号特大斜拉桥的带减振器的斜拉索做参数识别。研究表明: 若拉索多阶振动频率能够被获得，则通过PSO 算法得到的T，EI，K，εL 等拉索参数是可靠的。

关键词: PSO 算法, 减振器, 参数识别, 斜拉桥
