Verification Of Large Scale Dynamic Soil Model Tests Through Numerical Analysis

This study presents numerical evaluation of large scale dynamic soil testing in a new laminar soil container setup. A dry sand sample was instrumented with embedded accelerometers and linear variable differential transformers (LVDT) connected to the container from an outside frame. The large scale soil sample was tested under dynamic sinusoidal and earthquake motions generated on the shaking table. The measured accelerations and LVDT data were processed and the free motion of the sand sample in the middle of the container at different depths was investigated. One dimensional site response of the soil sample was compared with a 1D soil model prepared in site response analysis software program DEEPSOIL v7.0. The results demonstrated that the measured accelerations in good agreement with the computed site response output data.
