Geo-centrifuge test in the evaluation behavior of soil-structure system under earthquake loading

Earthquakes are often difficult to predict and have the potential to cause great damage to people and property, most of which are related to the collapse of the soil-structure system and geotechnical problems. Currently, to evaluate the dynamic behavior of structures and ground under the effect of earthquake load experimentally, there are two main methods: the 1-G shaking table model experiment (1-G shaking table test) and the centrifuge model experiment (geo-centrifuge test). Different from the 1-G shaking table test, the model is accelerated to an appropriate level in the centrifuge test. Thus, the self-weight of the soil and structure can be increased correspondingly at the appropriate rate, and the behavior of the soil-structure system can be described similar to reality.
