包头地区工程场地土层地震反应分析

Analysis of the soil layer seismic response in construction sites of Baotou area

为了建立包头地区土层地震反应分析模型,在包头地区工程场地地质的基础上,通过的数值解析方法,建立层地震分析模型,得到了场地50年超越概率63%、40%、10%、2%四个概率水平的地表和不同深度位置的地震动参数,反应谱值等设计参数。本文研究结果可作为轨道交通建设工程抗震设防的参考依据,具有实际参考价值。

Based on the seismic geological conditions in Baotou area,the seismic response of soil layer was analyzedsional equivalent linear method on the basis of seismic risk analysis. The peak accelerations of 63years at different locations of the site were calculated, and the ground motion parameters and response els in different depth were obtained. The results can be used as reference for seismic fortification in this area,for seismic fortification of rail transit construction projects.
