Abstract: It is very significant for engineering guide to study on earthquake ground motion parameter in high-fill project.According to the foundation parameter of some airport,the site modells of different filling thickness,different degree of compaction,different thickness of the original soil base is build up.Contrasting the research calculation result,the variety characteristic of the earthquake ground motion parameters of high-fill project under different site categories is acquired through actual data.The research result will provides valid parameter and science reasonable basis for the engineering design.
