摘　　要：声导则中,公路交通噪声预测模式是一个半经验模式。通过对该模式进行详细的推导,以正确理解导则模式的来龙去脉,然后对该模式的相关问题给出了深入分析,以便在实际工作中正确运用及进一步开发公路噪声预测模式。讨论表明,在实际工作中,声源处理、参考点位置、多车道、气象条件等模型参数,应结合具体情况进行合理修正。并建议换一种噪声预测建模思路,不采用导则中的半经验模型,而采用概率分布的形式,对影响噪声水平的车流速度、流量和源强等变量进行描述建模。In the Technical Guidelines for Noise Impact Assessment,highway traffic noise prediction model is a empirical model. In this paper,the guideline model were derived in detail in first,to correctly understand the model. And then,the related problems of the model were given in- depth analysis,in order to correct use the model in actual work,and further development of highway traffic noise prediction model. The discussion shows that,the model parameters such as sound source treatment,reference point location,multilane highways,meteorological condition and so on, should be reasonably modified in combination with the actual situation. And a suggestion is recommended that the noise predictive modeling ideas should not using the semi-empirical models,and takes the form of probability distributions,which describe the modeling using the affecting the noise level variable,such as traffic speeds,flow and sound sources.
