摘 要:目的了解高架轻轨噪声对周围环境的影响。方法对南京市地铁一号线高架轻轨运行时对周边南京医科大学教学楼及办公楼、明德医院门诊及住院部和商店的噪声影响情况进行测定。结果 (1)学校教学楼1、3、5楼在列车通过时(开窗状态)测得的噪声值分别为57.0、57.4、56.3 d B(A),均超标〔>55 d B(A)〕;办公楼1、3、5楼在列车通过时(开窗状态)测得的噪声值分别为58.9、63.8、63.9 d B(A),均超标。(2)医院病房楼1、3楼在列车通过时(开窗状态)测得的噪声值分别为66.7、61.5 d B(A),均超标;病房楼1、3、6、9楼在列车通过时(开窗状态)测得的噪声值分别为60.3、55.5、57.1、56.9 d B(A),均超标。(3)商场1、2、3楼在列车通过时测得的噪声值分别为67.2、65.8、68.1 d B(A),亦超标〔>60 d B(A)〕。(4)列车通过时关窗与开窗相比能平均降低噪声10.6 d B(A),关窗时噪声基本不超标。结论列车通过时,周边学校、医院、商场测得噪声值(开窗状态)均高于声环境质量标准规定的限值;关窗能明显降低高架轻轨噪声。同时应采取有效措施降低高架轻轨噪声。Objective To understand the impact of the elevated light rail noise on the surrounding environment in the city.Methods The noises were determined in the university( teaching building and office building),the hospital( outpatient building and patient building) and the market around the line one light rail in Nanjing. Results( 1) When the train through,the noises on the first,third,fifth floor of the teaching building( windows were open) were 57. 0,57. 4,56. 3 d B( A) respectively. When the train through,the noises on the first,third,fifth floor of the office building( windows were open) were 58. 9,63. 8,63. 9 d B( A). All of them went beyond the limit 55 d B( A).( 2) When the train through,the noises on the first、third floor of the outpatient building( windows are open) were 66. 7 d B( A),61. 5 d B( A). When the train through,the noises on the first,third,sixth,ninth floor of the patient building were 60. 3 d B( A),55. 5,57. 1,56. 9 d B( A). All of them went beyond the limit 55 d B( A).( 3) When the train through,the noises on the first,second,third floor of the market were 67. 2 d B( A),65. 8 d B( A),68. 1 d B( A). All of them went beyond the limit 60 d B( A).( 4) Closing the window could reduce the noise 10. 6 d B( A) in average while the train through. Conclusion When train through,the noises of the school,the hospital,the market all go beyond the limit( windows are open). Closing the window can reduce the noise obviously. Something must be done to reduce noise pollution.
