The spatial variation of seismic ground motion is examined using data obtained at the LSST (Large-Scale Seismic Test) site in Lotung, Taiwan. The time dependence of that spatial variation is also examined. It is found that the effects from the 1/4 scale containment model and the backfill can be observed in the recorded acceleration data up to 5 m from the model. From the data (excluding stations close to the model and some improper records) a coherence analysis is carried out and spatially random models of ground motion are developed. The developed model is found to be consistent with an alternative model based on data over long distances. Using this random model, the effect of spatial variation in ground motion on the soil-structure interaction system is also examined. キーワード（英）： - 記事区分： - 区分 　　　委員会論文集
