| Abstract: | The effects of overburden thickness and topography on earthquake ground motion are ana- lyzed in accordance with the particularity of loessial sites. An experiential method of evaluating ef- fects of overburden thickness and topography on ground motion is proposed based on a lot of sta- tistical data of seismic response of sites, which can serve as the basis for preventing and reducing the loessial disasters caused by earthquakes. |
