摘　　要：城市轨道交通建设中,为了减少施工期间的噪声对施工人员和周边居民造成的负面影响,对城市轨道交通工程施工噪声进行监测和管理。通过采用噪声传感器和声级计对城市轨道交通工程产生的噪声进行监测,在此基础上,利用Cadna/A软件模拟预测噪声特性及其分布。结果发现,项目施工场界噪声昼间最高达89.5dB(A),噪声排放超过国家标准限值。为减轻噪声影响,根据噪声特点从声源处、传播过程中、接收处和施工规划等方面提出降噪方案,预测降噪量约为10~20dB。填补了城市轨道交通工程施工噪声方面的研究空白,为中国城市轨道交通工程的施工噪声控制提供了有价值的参考。Noise pollution is considered an important aspect of global environmental issues.The construction of urban rail transit is gradually increasing,leading to excessive noise pollution in rail transit projects.The noise during construction has negatively impacted both the construction workers and residents in the surrounding neighborhoods.Therefore,monitoring and managing the noise is very important.In this study,noise sensors and sound level meters were employed to monitor the noises produced in an urban rail transit project.Then,Cadna/A software was utilized to simulate the noise characteristics.Based on the results,it was found that daytime noise has a maximum of 89.5dB(A),which exceeds the standard.To alleviate the noise impacts,a noise reduction scheme was put forward.The implementation of the noise reduction scheme is predicted to have an effect,resulting in an approximate 10-20dB reduction in noise level.The implementation of the scheme will allow the construction noise of the case projects to meet the national standard.This study addresses the research gaps related to construction noise in urban rail transit projects and provides valuable references for the noise control of urban rail transit projects in China.
