An international joint research program called "HLSST" is proceeding. HLSST is Large-Scale Seismic Test (LSST) to investigate Soil-Structure Interaction (SSI) during large earthquake in the field in Hualien, a high seismic region in Taiwan. In this site a l/4-scale model building was constructed, and the model building and the foundation ground were extensively instrumented to monitor structure and ground response. To accurately evaluate SSI during earthquakes, geotechnical investigation and forced vibration test were performed during construction process namely before/after base excavation, after structure construction and after backfilling. This paper describes the change of the shear wave velocity (Vs) measured by the field test. Discussion is made on the effect of overburden pressure during the construction process on Vs in the neighboring soil and, further on the numerical soil model for SSI analysis. ƒL[ƒ[ƒhi‰pjF - ‹LŽ–‹æ•ªF - ‹æ•ª @@@ˆÏˆõ‰ï˜_•¶W
