摘　　要：我国现行铁路环境噪声预测方法基于轮轨滚动噪声特性构建,部分预测参数直接引用了国外的研究成果,预测精度不高,而且无法用于高速铁路噪声预测。在对我国铁路环境噪声源分析的基础上,通过理论推导及分析,提出铁路环境噪声预测方法修订建议,即速度修正、垂直指向修正及声屏障插入损失修正,进一步完善普速铁路环境噪声预测方法,基于多声源等效模型构建高速铁路环境噪声预测方法,经现场试验验证,可以满足铁路环境噪声预测要求。The current railway environmental noise prediction method in China is based on the characteristics of wheel-rail rolling noise.Since some prediction parameters are directly quoted foreign research results and the prediction accuracy is not so high,therefore they cannot be used for high-speed railway noise prediction.Based on the analysis of railway noise sources in China, this paper puts forward some suggestions such as speed correction,vertical direction correction and sound barrier insertion loss correction,so as to further improve the prediction method of environmental noise of general speed railway through theoretical derivation and analysis.Based on the multi-sound source equivalent model,a high-speed railway environmental noise prediction method is constructed in this paper,which can meet the requirements of railway environmental noise prediction after field tests.
