Abstract

Seismic subsidence deformation characteristics of intact loess and dynamically compacted loess were studied through centrifuge scale-down test.Results showed that the value of seismic subsidence of loess increased with increasing in moisture content and depth of loess.The dynamic compaction of loess can completely eliminate the seismic subsidence within a certain effective depth.
