| 摘 要： | 为研究桩-土-结构动力相互作用对输电塔线体系风振响应的影响，在ANSYS有限元软件中建立桩-土-输电塔线体系的有限元模型，将由Matlab按自回归（autoregressive，AR）法模拟计算出的脉动风荷载时程作用在有限元模型上进行风振响应分析。以具体的输电塔线体系为例，在软土和硬土两种不同的场地条件下对输电塔线体系进行分析，并将结果与不考虑桩-土-结构动力相互作用的输电塔线体系风振响应分析进行对比，得出不同条件下桩-土-结构动力相互作用对输电塔线体系风振响应的影响规律。 |

| Abstract： | In order to study the effect of pile-soil-structure dynamic interaction on the wind vibration response of transmission tower-line system, the finite element model of pile-soil-transmission tower coupled system was set up by ANSYS. The fluctuating wind loads simulated by Matlab according to autoregressive (AR) method was forced on the model in order to analyze the wind vibration response. The wind vibration response of a pile-soil-transmission tower system under two different site conditions (soft soil and hard soil) were calculated, and compared with the result that does not consider the effect of pile-soil-structure dynamic interaction. From the comparison, the influence of pile-soil-structure dynamic interaction on wind vibration response of transmission line system has been concluded. |
