摘要
简要介绍了铁路工程项目噪声回顾评价及其工作方法 ,通过实测和数理统计 ,分析了产生铁路噪声环境影响预测误差的主要原因 ,针对如何提高预测的准确性提出了改进建议。
This paper makes a brief introduction to the working method of noise review assessment for railway projects.It analyses the railway noise characteristics of railway lines and stations and yards by type and also the causes of forecast errors from the aspects of traffic flow change,noise source strength,whistling,etc.It verifies the accuracy of the original forecast result.Meanwhile,it proposes improvement recommendations in the light of the measurement and calculation method to the noise source,such as railway noise.It provides a conception for improving environmental impact forecast technique of railway noise.
