摘要

This study adopts 3D-FEM with numerical and statistical approaches to analyze the dynamic response of a viaduct-ground system with an open trench during maglev train operation. In such a way, a realistic maglev train-viaduct-ground system is implemented and validated through comparative analysis with data from field tests. Then, an investigation on ground-borne vibration when an open trench is used resulted in a description of the trench’s operational mechanism, which can be used to better attenuate vibrations in buildings. A statistical study highlighted the key characteristics that should be specifically considered in trench design to enhance performance. A model was subsequently developed to forecast the attenuation rate of ground-borne vibration in an edifice near the viaduct, based on trench parameters.
