摘　　要：采用数值方法进行边坡场地—结构动力相互作用分析,包括水平成层场地和边坡场地的自由振动及场地卓越周期、场地—结构系统的地震响应,讨论了不同场地自由振动的性态及场地—结构系统共振的条件和特性。The numerical method is employed to perform the analysis on the dynamic slope-sitestructure interaction. The free vibration and the predominant periods of the horizontal layered site and the slope site are included in the analysis. The seismic response of the site-structure system is also analysed. The free vibration behaviours of different sites and the condition and the behaviour of resonant vibration of the site-structure system are discussed.
