摘　　要：对某风电场风力发电机地基进行现场加速度测试,在土动力性能室内试验的基础上利用有限元对风机基础—地基系统进行数值模拟。在地基加速度的峰值、衰减规律和频率上,现场测试与计算结果吻合较好,验证了动力数值分析模型及相关参数取值的合理性,为建立风机振动对周围环境影响的数值模型提供了依据。The site test for acceleration of a wind turbine ground was done.Based on laboratory dynamic properties test of the site soils,the finite element method is utilized to simulate the wind turbine foundation and ground vibration.The simulation results response,like the peak acceleration values,the frequencies and the rule of acceleration attenuation,agree with the site test results,showing that the dynamic simulation model and the corresponding parameters are appropriate.This simulation process can be used as reference for simulating the ground vibration caused by wind turbine and assessing its influence on the environment.
