Ground vibration induced by high-speed trains can reach levels that cause annoyance to humans and interruption of sensitive instrumentation. To address this issue, the characteristics of ground vibration induced by Taiwan high-speed rail on bridge structures are evaluated using a wide range of fieldmeasured data. The measurements for analysis consist of various foundation types, geological conditions, and train speeds. Both near-field vibration (25 m from track center) and far-field vibration propagation are evaluated. Specific influence factors for ground vibration assessment are also presented.
