Annoyance level of metro train-induced environmental vibration based on evaluation index conversion method

Here, to study the relation between metro train-induced environmental vibration level and human subjective annoyance, the index conversion algorithm was used to derive the conversion relation between the maximum Z-vibration level VLZ,maxand the quartic vibration dose value (VDV). Coefficients to be determined in the conversion formula were fitted through on-site testing. Drawing lessons from study results of exposure-response relation based on the index VDV, exposure-response curves based on the index VLZ,maxwere obtained, and the evaluation of resident vibration annoyance level based on the recommended index according to Chinese national standards was preliminarily realized. The study showed that increase in number of passing cars per unit of time can lead to increase in the proportion of human annoyance; resident annoyance levels corresponding to recommended vibration limits in national standards GB 10070, GB/T 50355 and GB 55016 are basically consistent with those corresponding to limit values in international standards; the proportion of high annoyance levels corresponding to the strictest limit value is about 3% . © 2024 Chinese Vibration Engineering Society.
