《环境影响评价技术导则声环境》(HJ2.4-2009)对于公路道路交通噪声预测模式中的单车辐射声级没有给出固定的计算方式,本文对某两条城市道路采用实际环境影响评价中常用的各种预测模型计算并与实测值进行分析比较,结果发现,单车辐射声级采用2006版规范进行计算,同时结合2009新导则的预测模型得到的预测值与实测值较为相符。 The Technical Guidelines for Environmental Impact Assessment Acoustical Environment (HJ2.4-2009) does not give a fixed calculation method for the radiation level of a bicycle in the road traffic noise prediction mode. In this paper, the actual environmental impact assessment of two urban roads The results show that the radiation level of a bicycle is calculated according to the 2006 version of the specification, and the predicted value obtained by the prediction model of the 2009 new guideline is in good agreement with the measured value.
