摘　　要：本文旨在建立机动车单车辆的基础噪声排放模型,通过对大中小车辆在加速、减速、匀速及怠速状态下A计权声压级进行测量,运用回归分析方法拟合实验数据,得到考虑车型和行驶状态的水泥路面机动车单车辆噪声排放模型,并利用另一部分实测数据进行对比验证。误差分析显示:比较《公路建设项目环境影响评价规范(JTG B03-2006)》中的噪声模型,本研究建立的单车辆噪声排放模型预测精度更高。The article aimed at establishing a basic noise emission model of the single vehicle, in this research, the A-weight sound press levels of vehicles under different types and driving states including uniform velocity, acceleration, deceleration, and idle state are tested on cement road. The emission model of single vehicle＇s noise source considering about vehicle type, velocity and acceleration was obtained by applying regression analysis method to testing data fitting. And then this model＇s data compared with the vehicle＇s noise source intensity prediction model in specifications for environmental impact assessment of highways （JTG B03-2006） to testify its validity. It is demonstrated that the single vehicle＇s noise emission model set up by this research predicts more accurate and matches the actual situation better.
