摘　　要：为了降低道路的噪声,以某国道为依托工程,在对材料的调查分析基础上,通过构建低噪声路面动力学分析模型,并赋予依托工程的道路实际材料参数,仿真计算得到普通路面与试验路面的时间—位移,时间—速度,时间—加速度关系曲线,建立了降噪路面的时间—位移关系数学模型;通过检测普通路面与试验路面的噪声,发现2种路面材料的噪声值均呈现随车速的增加而增加的规律,得到试验路面相比普通路面可有效的降低噪声值5-6分贝,为道路噪声的降低提供了理论依据。In order to reduce the noise of the road, the dynamic analysis model of low-noise road has been bound, based on the investigation and analysis to data of someone national highway project. Time-placement, time-speed, time-acceleration curves are got by calculating with computer simulate. By detecting the noise of ordinary and test road, we find that noise values of the two road materials both increase with the increase of vehicle speed and 5-6dB noise is effectively reduced on test road. The study provides a theoretical basis for reducing road noise.
