摘要
对公路交通噪声预测计算的准确性从预测模型、源强及主要参数的确定等几个方面进行了分析论证 ,指出不同形式预测模型的采用、不同源强的选取以及参数的确定对公路交通噪声的预测计算结果都有明显的影响。并分析了工程可行性研究阶段因公路线位的不准确性而导致预测结果与实际不符的现象。
The accuracy of highway traffic noise prediction was analyzed and demonstrated form the aspects of prediction models,noise source intensity and main parameter values.It is suggested that the adoption of different models,source intensity and parameter values have obvious influence on the calculation results of highway traffic noise.The phenomenon that prediction results do not suit to the practice due to the imprecision of proposed alignment in the phase of project feasibility study was analyzed also.
