摘　　要：开展快速公交系统(Bus Rapid Transit,简称BRT)与直线式公交系统的公交站台噪声防控措施设计及降噪效果评估对减轻站台候车乘客噪声污染意义重大。以两种类型公交站台为对象进行声屏障、绿化林带、隔声窗3种防控措施设计,并对其降噪效果进行量化评价。研究结果表明:声屏障改进设计衰减量为5.8~7.7 dB,改进设计后昼间(6:00—22:00)噪声值全部达标;绿化林带设计衰减量为0.53 dB,改进设计后超标量为0.07~0.37 dB;6 mm和12 mm单层玻璃隔声窗设计衰减量为30 dB和36 dB,(5+6A+5)mm和(6+9A+6)mm双层玻璃隔声窗设计衰减量为37 dB和44 dB,改进设计后6 mm单层隔声窗不满足高标准要求噪声限值,超标率100%,12 mm单层隔声窗、(5+6A+5)mm和(6+9A+6)mm双层隔声窗均满足高低标准要求噪声限值,超标率0%。因此推荐交通管理部门采取公交站台声屏障及噪声敏感建筑物安装隔声窗的方式降低公交站台及周边环境噪声污染。It is important to design noise prevention and control measures and assess the noise reduction effect at Bus Rapid Transit(BRT)and Linear Bus System stations for passengers to reduce noise pollution.This paper designed three types of prevention and control measures of the sound barrier,green belt,and acoustic window,for the two types of bus stations,and quantitively assessed their noise reduction effects.The results showed that the improved noise attenuation of the sound barrier was 5.8-7.7 dB,and after improving the design,the daytime(6:00-22:00)noise values all met the standards.The designed noise attenuation of the green belt was 0.53 dB,and the improved design exceeded the standard by 0.07-0.37 dB.The designed noise attenuations of 6-mm and 12-mm single-glazed acoustic windows were 30 dB and 36 dB,respectively,while those of(5+6A+5)mm and(6+9A+6)mm double-glazed windows were 37 dB and 44 dB;after improving the design,the 6-mm single-glazed window did not meet the noise limit value of the high standard requirement,which exceeded the limit value by 100%,while other three types of windows all met the high and low noise limits,with an exceedance rate of 0%.Therefore,it was recommended that the traffic management department adopt sound barriers at bus stations and install acoustic windows in noise-sensitive buildings to reduce noise pollution at bus stations and the surrounding environment.
