Study on Peak Acceleration of Ground Motion Based on Collapse Resistance in Hefei Urban Area
摘要
Abstract
According to the geomorphology and the Quaternary distribution characteristics of Hefei urban area,36 typical boreholes are selected,and the one-dimensional equivalent linear method is used to calculate the ground motion parameters under three different exceedances probability conditions,and the peak acceleration amplification coefficient and the law of rare ground motion and basic ground motion amplification are studied.The results show that the overburden thickness,geomorphic features and soil structure have significant effects on the peak acceleration and amplification coefficient of ground motion,and there is a certain regularity.关键词
