摘　　要：采用江苏8条高速公路共18组噪声实测数据对《环境影响评价技术导则声环境》(HJ2.4-2009)公路交通噪声预测模型计算结果进行验证。根据验证结果和误差原因分析,提出针对单车辐射声级计算公式的修正方案。修正后模型计算值与实测值的差值平均值控制在1dB(A)以内。The highway traffic noise prediction model of Technical Guidelines for Noise Impact Assessment(HJ2.4-2009)was tested by 18 groups of noise monitoring data from 8 expressways in Jiangsu Province.The modification method to the calculation formula of radiation sound level of single vehicle was raised,based on the testing result and the cause analysis of errors.The average difference between the calculated value by modified model and the monitoring data was controlled in 1dB(A).
