【摘要】 以无锡市区某工程场地软土动力特性和地脉动频谱结构为研究对象,对该场地进行了地脉动的测试及频谱分析。根据对场地实测的地脉动数据进行分析,并结合现场勘察报告结果,对工程场地的脉动频谱曲线进行了分类,通过计算分析得出各测点的脉动振幅、场地卓越频率和卓越周期等,为以后的工程建设设计提供一定的参考依据。更多还原

【Abstract】 A study of seismic failure mechanism of soft soil project site in Wuxi is presented.The characteristics of frequency-spectrum structure and response of ground soils,including soft soils and the frequency of ground micro-tremor,were investigated.The spectrum curves of project site were classified according to the dates of ground micro tremor and the results of survey report.The pulsation amplitude,predominant frequency and predominant period of the site were calculated,and the design of this project site could refer to the results of this study.更多还原
