摘要
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,by analysing the 80 power spectra of the observational ground microseisms obtained in different sites of Urumqi city.It is shown that ground microseisms are obviously characterized by spectra.These charactcri"sties are concerned with the soil of sites,and vary with the variation of soil varieties,finally,we have divided the urban districts into four subregions-according to the types of the spectra.
