Analysis Model of Ground Vibration Propagation for High-Speed Trains
Two simple analysis models for wave propagation, the Bornitz and Wiss methods, are examined in order to evaluate their reliability in measuring ground vibrations induced by high-speed trains. First, basic soil background vibrations for various geological conditions are established. Then, field measurement data for high-speed trains on bridge and embankment structures are used to evaluate the analysis models of wave propagation. The analysis models consider the effect of the basic soil background vibration. Based on these analyses, the analysis methods of Bornitz and Wiss can be used to achieve a reasonable prediction of ground vibration attenuation for high-speed trains. Soil background vibrations exhibit relative differences in measured locations, thereby significantly affecting the ground vibration attenuation of passing high-speed trains. The attenuation coefficients of both embankment and bridge structures become larger and appear to converge in a narrow range when the basic soil background vibration is omitted, especially in embankment structures.
