摘　　要：为研究地铁列车运行所引起的建筑物内振动对人体暴露于全身振动的舒适度影响,基于广州地铁某线路的现场实测,结合国内外相关振动标准,获取适用于评价地铁运行所引起的邻近建筑物内人体舒适度的振动限值标准,同时分析人体振动感知比(WODL)、竖向四次方振动剂量值(VDVz)和烦恼率3种评价指标对人体暴露于全身振动的舒适度的影响。分析结果表明:采用Z振级对建筑物内振动进行评价时,建议结合建筑物室内振动限值和人体振动舒适度的容许振动计权加速度级共同进行评价;在峰值因数较小时,WODL能够准确评价人体舒适度,对于地铁振动敏感度高,VDVz能更准确反映地铁持续振动对建筑物内人体暴露于全身振动舒适度的影响,烦恼率可以量化振动舒适度,适合用来评价瞬时最大加速度对舒适度的影响,并能用来评估同一振动场所中由于振动而产生烦恼反应的人数。以上结论可为评价地铁列车运行所引起的建筑物内振动对人体暴露于全身振动舒适度影响提供参考。The influence of internal vibration of building structures induced by subway train operation on human exposure comfort degree of whole-body vibration is studied.Based on field measurement data of a subway line in Guangzhou and according to the relevant vibration standards at home and abroad,the vibration limit value standard for evaluating human comfort in adjacent buildings caused by subway operation is obtained.Moreover,the influences of three evaluation indexes,such as human vibration perceptivity ratio(WODL ratio),vertical fourth power vibration dose value(VDVz)and annoyance rate,on the comfort degree of human exposure to whole-body vibration are also analyzed.The results show that when the z-vibration level is applied to evaluate the vibration inside buildings,it is better to consider the vibration limit value of buildings and admissible vibrator weight acceleration level of the human vibration comfort simultaneously.When the peak factor is small,the human comfort evaluated according to WODL ratio is more accurate.The VDVz can properly reflect the influence of continuous subway train operation on comfort degree of human exposure to whole-body vibration due to its high sensitivity to subway vibration.The annoyance rate can quantify the vibration comfort,so it is suitable to evaluate the influence of instantaneous maximum acceleration on human comfort and estimate the number of people with annoyance response to vibration in the same vibration place.The conclusions above provide a useful reference for evaluating the comfort degree of human exposure to whole-body vibration caused by subway train operation.
