Abstract
In order to improve the stability of seismic design, it is necessary to understand the dynamic behavior of soil subjected to earthquake lodings. The shaking table test is one of the important experiments in geotechnical earthquake engineering research. In the vibration-proof tests of various ground and building models and the seismic performance evaluation of important facilities, a 1g shaking table test can be performed according to the needs of the researcher, a specific seismic wave can be reproduced, or a vibration of a specific frequency can be repeatedly excited. The ground response obtained from the 1g shaking table test can predict the effect of real seismic waves on the ground, and it is easy to study earthquake countermeasures or ground damping.
In this study, the effect of boundary conditions was evaluated by location by creating a model slope in a soil tank, and it was compared with ABAQUS, a finite element analysis program. As a result of the comparative analysis, the experimrnt results are in good agreement with the numerical analysis results. It is judged that the most effective data can be obtained only when the slope model test is performed at a point of 50-100 cm far from the wall of the soil tank.
