Evaluation of the Effects of Vibrations Induced by Trains Simultaneously with Liquefaction of the Layer Below the Structure Nearby the Rail

This paper presents a study of the harmful effects of ground borne vibration induced by high speed trains. A model has been designed using ANSYS software to evaluate and predict nearby structure damage. Another effect of train vibration modeled in Ansys software is liquefaction from a green sand layer below the structure. A comparison has been conducted between predicted and real peak particle velocity inside the building.To excite the structure model, sample inputs for peak particle velocity are chosen from recommendations by ISO14837-1 standard. Frequency analysis of the output data from the software and comparing that with ISO14837-1 standard, results in prediction of some harmful effects. Output of Ansys software shows some harmful effects on building, such as floor deflection, column twist and destroy surface of walls.
