摘要
地铁站是人员密集的地下交通空间,内部环境的噪声控制标准与技术措施不仅影响使用者的的生理及心理健康,而且直接关系到突发事件下公共广播系统的语言清晰度能否满足安全疏散的要求,具有极为重要的现实意义。该文通过对地铁站公共区主要噪声源的频谱分析,依据目前我国现行的相关规范,提出了对不同类型地铁站噪声控制指标的合理化建议,并在此基础上整合了可行的技术措施,旨在推动和促进我国地铁站的安全、良性发展,为城市地下公共空间的防灾、减灾研究做出有益的探讨与尝试。
Since subway station is an underground traffic space with people close packed,noise control for its internal environment not only affect physical and mental health of users but also directly touches on whether articulation of public address（PA） system can satisfy requirements for safe evacuation under emergency,which are of high practical signif icance.According to spectrum analysis on main noise sources in public area of subway station,based on existing relevant regulations in China,rationalization proposals for noise control are put forward for different types of subway stations in the paper.On the basis of this,feasible technical measures are integrated to promote safe and sound development of subway stations thus beneficial discussion and attempt are carried out for disaster prevention and disaster reduction in urban underground public space.
