不同模式预测公路交通噪声的区别研究

文章在详细介绍常见公路交通噪声预测模式区别的同时,进行了不同公路项目的设定,对高速公路、一级公路、二级公路、三级公路、四级公路项目分别采用了上述预测模式进行预测,通过不同预测模式下不同公路项目交通噪声的对比、分析,得出"对于一般公路项目,适合在对车速、车型比等参数进行合理校核的基础上,采用HJ/T 2.4-2009中推荐模式进行预测;其它项目,适合通过类比同类项目的交通噪声影响的方法进行预测"的结论。由于本文采用的模式均为行业内认可的模式,其预测结果及表现特点有助于准确地反映和预测公路交通噪声。

Prediction of Road Traffic Noise using Different Models

The paper discusses the differences between the common road traffic noise prediction models. By setting different road projects, it predicts the road traffic noise to highway, first class road, second class road, third class road and fourth class road projects under the previous models. By comparing and analyzing the differences in performance gains, come to a conclusion that it＇s suitable for general highway project by checking the parameters such as speed, proportion of vehicles to predict the noise under the model in H J/2.4 - 2009. It will also provide reference for other projects.
