Mining explosions and railway transportation generally result repeated intermission vibrations (RIV). These vibrations, with relatively shorter duration and larger peak acceleration, often repeat several times in a day. A proper evaluation method of human response should consider both the non-stationary nature and the occurrence frequency of RIV. This result the evaluation process has some differences compared with that for ordinary stationary vibration. Current evaluation method for human vibration comfort is first reviewed in this paper. Then the vibration dose value (VDV) and frequency of vibration events are introduced to evaluate vibration comfort under RIV. At last part of the paper, two vibration cases, one for blasting and one for railway transportation, are analyzed to explain above evaluation process.
