城市轨道交通环境振动对人体影响的暴露-响应关系研究现况

Research Advance of the Exposure-response Relationship between Railway Vibration and Human Comfort

伴随我国城市轨道交通发展和人们环保意识增强,列车引起的环境振动问题日益受到关注。振动暴露-响应关系反映了客观振动水平与主观感受间的关系,是确定振动标准限值的重要依据之一。系统总结国内外针对列车环境振动对人体影响暴露-响应关系的研究进展,梳理国内进行振动评价的适用规范和舒适度评价采用的方法。研究表明:地铁振动扰民问题缺乏暴露-响应曲线的科学评判,基础调查研究的缺乏和振动指标换算的局限制约了振动限值的合理确定。建议开展地铁振动对人体影响的暴露-响应基础研究和国内外振动评价指标转换研究,为制定以人为本的振动限值提供理论基础,并实现国内外标准和研究成果的可比性和可借鉴性。

With the development of urban rail transit and the increase of people’s awareness of environmental protection in China,train-induced environmental vibration problem has been paid attentions increasingly.The vibration exposure and response reflect the relationship between the objective vibration level and human perception.It is one of the most importance bases to determine the vibration limit value.In this paper,the research advance of the exposure-response relationship between train-induced vibration impact and human comfort was summarized.The active domestic standard for vibration evaluation and commonly used assessment method of vibration comfort were reviewed.It is concluded that the problem of metro vibration annoyance is unlikely to be scientifically defined if the fundamental research on exposure-response curve is insufficient.The values of vibration limits are hardly to be reasonably determined if the basic data is not able to be obtained from either massive direct measurements in future or indirectly converted from international vibration standards.Therefore,in order to provide a foundation to make the people-oriented resident vibration limits and realize the comparing and referencing between national and international research results,research should be focused on two aspects:(1)fundamental research of the exposure-response influence of metro train-induced vibration annoyance on residents,(2)vibration description index conversion between national and international standards.
