摘　　要：针对某在建综合交通枢纽内高速铁路沿线高标准星级酒店噪声超标问题,分别采用几何声线法和统计能量分析法,建立铁路沿线噪声以及建筑室内噪声预测模型,研究列车高速通过及进出站时铁路沿线噪声分布特性和酒店内部噪声情况,讨论了声屏障对铁路沿线噪声、建筑外墙(窗)隔声以及酒店内部房间尺寸酒店内部噪声的影响规律。研究结果表明:(1)列车通过时,铁路沿线环境噪声水平将达到90 dB(A)以上,酒店内部噪声也将超过50 dB(A);(2)设立声屏障可有效降低铁路沿线噪声2~10 dB(A),同时提高建筑外墙隔声、增大室内房间面积可有效降低室内噪声16~18 dB(A);(3)在铁路声屏障和建筑外墙(窗)隔声都难以进一步有效降低沿线敏感建筑室内噪声时,可通过改变房间用途来使内部噪声满足标准要求。研究成果可为高速铁路沿线敏感建筑的噪声控制提供参考。Aiming at the problem of excessive noise in high-standard starred hotels along high-speed railway in an integrated transport terminal under construction,the prediction models of noise along the railway and indoor building noise were established by the geometric ray method and statistical energy analysis respectively.The distribution characteristics of noise along the railway and the noise conditions inside the hotel when trains pass through and enter or leave the station at high speed were studied,and the law of the impact of sound barriers on noise along the railway and that of sound insulation of exterior walls(windows)of building and room sizes of hotel on noise inside the hotel was discussed.The study results show that:(1)When a train passes through,the ambient noise along the railway will reach more than 90 dB(A)and the noise inside the hotel will also exceed 50 dB(A).(2)Sound barriers can effectively reduce the noise along the railway by 2~10 dB(A),and at the same time,improving the sound insulation of exterior walls of building and increasing the areas of indoor rooms can effectively reduce indoor noise by 16~18 dB(A).(3)When it is difficult to further effectively reduce the indoor noise of sensitive buildings along the line through railway sound barriers and sound insulation of exterior walls(windows)of buildings,the internal noise can meet the standard requirements by changing the room purpose.The results can provide a reference for noise control of sensitive buildings along high-speed railway.
