摘要
为研究地铁环境振动水平与人体主观烦恼度感受之间的关系,采用指标换算法,推导了最大Z振级VL_(z, max)与四次方剂量值(vibration dose value, VDV)之间的转换关系,并通过现场测试对转换公式中的待定系数进行了拟合。借鉴基于VDV指标的暴露-响应关系研究成果,得到了基于VL_(z, max)指标的暴露-响应曲线,初步实现了基于我国国标推荐指标的居民振动烦恼度评价。研究表明:单位时间内过车数目增多会导致人体产生烦恼度的比例增加;国标GB 10070、GB/T 50355和GB 55016中推荐的振动限值所对应的居民烦恼度,与国外标准中限值所对应的烦恼度基本一致,最严格限值对应的高度烦恼度比例约为3%。
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 VL z,max and 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 VL z,max were 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%.
