摘　　要：列车在行进中及进站和出站时伴随着滚动噪声和制动啸叫噪声等,使得车内和站内噪声加剧,对乘客的身心健康造成一定影响。通过对大连地铁2号线噪声进行调查与测试分析,找到了引起噪声过高的主要因素,得出车内噪声符合标准,但站台噪声超过标准要求。针对监测数据及分析结果,提出了对应的减振降噪措施,为地铁建设工程提供参考。When a metro train is in operation or passing in/out a station,the rolling noise and breaking noise will give riseto the noise at station that affects the surrounding environmentand especially the health of passengers.Through an investigationand test of the noise at stations on Dalian metro Line2,themain influencing factors that cause loud noise are detected,which meet the compartment criterion but exceed the allowablelimit of station standards.According to the investigation andanalysis of station noise,corresponding measures of vibrationand noise reduction are proposed.
