我国3条高速公路隧道污染状况调查

Chinese Expressway Tunnel Pollution and Control.

为了控制高速公路隧道内的空气和噪声污染，对中梁山、梧桐山和七道梁隧道进行了现场调查．结果表明，机械通风可以有效地控制隧道内的空气污染．隧道内的主要噪声源是交通流，其所产生的噪声远超过规范值，因此。

In order to control air pollution and noise pollution in expressway Tunnel,i.e.Zhong Liangshan Tunnel、Wu Tongshan Tunnel and Qi Daoliang Tunnel were studied,the site test result showed that machinery ventilate control effectively air pollution in tunnel,source of noise is traffic flow,their noise go beyond the values of standard,so it is important to study on technique reduced noise pollution.
