城市市区施工中的防音降噪措施

随着城市的现代化建设，越来越多的大型设备进入人们的视野，但随之而来的噪声污染却给居民的正常生活带来了严重的影响。现以地下工程施工工序为主线，通过工程实例分析了地下工程施工现场常见的噪声源，利用噪声控制原理主要从减弱噪声源、阻断传播途径两个方面进行噪声控制，通过工程实例进行效果分析，为城市市区施工噪声污染控制提供解决思路。

Noise Control and Reduction Measures for Construction in Urban Area

With the modernization construction of city, more and more large devices are coming into view. But the consequent noise pollution brings the serious influence on the normal life of the residents. Taking the construction procedure of underground engineering as an example, the common noise source in the construction field of underground engineering is analyzed through an engineering case. The noise control principle is used to control the noise mainly from two aspects of weakening the noise source and cutting off the route of transmission. The effect analysis on the engineering cases can provide the solving ideas for the control of noise pollution from the construction in the urban areas.
