摘 要:为研究城市轨道交通高架和地下站台噪声的规律和特点,选取某条线路中的3个高架站台以及3条线路中的7个地下站台进行实地测量,并对测量结果进行分析。研究结果表明:地下站台L_(Aeq)值都低于标准限值80 d B(A);站台的中心测点列车进站L_(Aeq)值和列车出站L_(Aeq)值都非常接近,使用T检验结果得出各站台中心测点列车进站L_(Aeq)值和列车出站L_(Aeq)值不存在显著差异(P>0.05);站台测量时要考虑大客流带来的喧闹声;站台最大噪声值是列车出站时,位于站台列车车头停止位置。This paper studies the noise characteristics of urban railway transit platforms,including elevated and underground stations,so as to provide references to noise measurements in practice. Platform noise of three elevated stations for a railway line,as well as seven stations for three metro lines,were measured and analyzed. The results show that L_(Aeq) values of underground stations is below the standard limit 80 d B( A). L_(Aeq) values at middle platforms are very close when trains are pulling in or pulling out,for both elevated and underground stations,as well as island and side platforms. The t-text demonstrated that there is no significant differences between L_(Aeq) values at middle platforms when trains are coming and going( P 0. 05).When measuring stations noise,it is necessary to pay attention to noise from massive passengers. The results also show that the maximum L_(Aeq) value on platform is located at the train head position when the train is pulling out.
