| 摘 要： | 广深线准高速铁路是我国第一条准高速铁路，其开通前后铁路环境噪声对居民影响程度必将产生变化。通过现场测试，采用铁路环境噪声冲击指数，分析评价准高速铁路对环境噪声的实际影响。结果表明，广深线准高速铁路开通后，石龙镇敏感地段铁路环境噪声冲击指数有所下降，高噪声居民下降率昼间约为２２．６％，夜间约为２３．２％。

| Abstract: | Guangzhou Shenzhen Line(GSL) is the first quasi high speed railway in P.R.of China.The noise level around GSL has been changed compared with before.Based on the mass data collected around GSL,this paper analysis and evaluates the real effect of noise level to resident under\ the technical method named as noise impact index(NII).The research indicates that NII level in sensitivity area,say Shilong,has been reduced after GSL open,the reduction in high noise level area in day and night is 22 6% and 23 2% respectively. |
