Abstract


With the rapid development of our domestic economy, the pace of the track traffic construction in some middle or large scale of cities is speeding up by year. The urban track traffic contributes a lot to our country’s economy, but it also brings about the correspondent negative influence to the environment near the railway as well. Considering the significant effect of the noise which caused by the track traffic, some negative impacts are sure to take place to the surroundings along the tracks. Noise is the major factor which leads to the environmental deterioration of the surroundings along the tracks. We are short of the technology of acceptance check and evaluation method. Owing to the incompleteness of relative standards and technical specification in monitoring and acceptance check process when the construction of urban track traffic project finishes, the unit of acceptance check and monitoring system demonstrate disunion in monitoring methods, and factors, frequency, content, data statistics and evaluation of the examination result.This essay sets down the acceptance check technology work procedure and main work content of " Technical Specification in Environmental Protection Acceptance Check When the program of the Construction of Urban Track Traffic Completes". It confirms the work range of the monitoring of these programs, selecting the principles of voluntary standards, and the emphasis of pollution abatement and exhaust analysis, assuring the quality control in setting spots, sampling, testing and the process of analyzing statistics data. At the same time, it also checks and accepts the technical requirements of the monitoring method, monitoring report arrangement and the evaluation of the monitoring result.This essay fully collects the international related information. It discusses the common factors and ways of evaluation of traffic noise. Then it confirms that the evaluation signal which is proper to represent our urban track traffic noise is Leq. Then, by comparing the differences and similarities of related track traffic noises standards in domestic and abroad, it points out the drawbacks in the related national standards now in use. Finally, it comes up with the computing method of Leq, which confirms to the objectionable reaction, on the basis of the statistics data given by the survey of the objectionable high annoyance of inhabitants who live near the railway.
