Description/Abstract

A semi-analytical model is used to predict ground vibration from trains running on the surface of the ground. Field measurements of vertical vibration at a site adjacent to a railway line in Southern England have been used to validate the model. Measurements using impact excitation were carried out first and are used to identify the compressional and shear wave speeds of the soil, the number of layers and their depth. The sensitivity of the vibration response to the various parameters is investigated. Measurements of vibrations from passing trains are then compared with predictions using the model, showing good agreement.
