摘　　要：为解决高速铁路运行时产生的噪声问题.减少对车内乘客及设备产生的不利影响,结合中国高速铁路运输实际,以哈大高铁为例,通过噪声衰减系数的修正,对北陆高速铁路噪声预测算法进行了改进,并分析了哈大高速铁路噪声的组成;结合噪声衰减原理,对哈大高速铁路的噪声声压级进行预测,得出最终衰减的噪声声量级67.44 dB;通过声屏障控制措施的实施,有效降低噪声对环境的影响.结果表明,基于改进的北路算法研究,对中国高速铁路的噪声预测、控制及环境的保护具有一定的参考价值.In order to solve the noise problems of high-speed railway runtime-generated and reduce the adverse effects on passengers and equipment inside the cars, this research combined with Chinese high-speed railway transportation reality and took Harbin-Dalian high-speed railway for example. First of all, this study improved Beilu railway noise prediction algorithm via correcting coefficient of noise attenuation, and analyzed the compositions of Harbin-Dalian high-speed railway noise; then combined with noise attenuation principle, the Harbin-Dalian high-speed railway noise levels were predicted, the final attenuation result of noise sound levels was 67.44dB; finally, the noise impact on the environment can be reduced effectively via implement of control measures, such as sound barrier. The results show that research based on improved Beilu algorithm has a certain reference value on Chinese high-speed railway noise prediction, noise control and environmental protection.
