铁路噪声环境影响预测误差分析

简要介绍了铁路工程项目噪声回顾评价的工作方法，从车流变化、声源源强、鸣笛等方面分析了线路类和站场类铁路噪声的特征及预测误差产生的原因；论证了原预测结果的准确性，针对列车等铁路声源的测量、计算方法提出了改进建议，为铁路噪声环境影响预测方法的改进提供了思路。

Analysis on Environmental Impact Forecast Error of Railway Noise

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 foreacast 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.
