本文通过对乌鲁木齐市地震小区划的80个地面脉动观测点所得功率谱分析结果表明,乌鲁木齐市地面脉动具有明显的频谱特征,而且这种特征与场地土类型密切相关,随着场地土不同显示出明显的差异。根据谱型把市区分为四个小区。
In this paper, power spectrum analysis results of 80 ground-based pulsation observation points in the sub-zoning of the Urumqi earthquake show that ground pulsations in Urumqi have obvious spectral characteristics, and this feature is closely related to the soil type of the site. Significant differences. According to the spectrum of the city is divided into four quarters.
