海上风电单桩基础周围土体地震液化分析
Study on Seismic Response and Liquefaction of Soil Around Pile Foundation of Offshore Wind Power
摘要
Abstract
The paper estimates that if the soil around Pile Foundation of Offshore Wind Powerin the Yellow River Delta would liquefy with both the finite element analysis of seismic response and the shearing force comparison method.Via comparison of different elements,the influence of the single pile foundation is summarized.The study found that the soil below 12 m would not liquefy because of the effective stress of above layers.The single pile foundation constraints the soil in it effectively,meanwhile increasing force of the soil around it.The paper implements acceleration along the X axis,so that the soil elements locating along the X axis subject much more stress than those along the Y axis.关键词
