Research on Construction Noise Monitoring and Noise Reduction Measures of Urban Rail Transit Projects
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.
