| 摘 要： | 为了分析《环境影响评价技术导则声环境》(HJ 2.4—2009)中将道路声源简化为1条位于道路中心线处的线声源与按照车道数简化为多条线声源之间的误差,针对不同宽度的道路,推导了多条线声源与1条线声源在接收点噪声影响的误差计算公式,并基于Predictor-lima预测软件预测和现场噪声衰减规律实测进行了验证。研究结果表明,对于接收点到道路边缘的距离大于道路宽度的情况,可简化为1条线声源;对于接收点到道路边缘的距离小于道路宽度的情况,应按照车道数简化为多条线声源。

| Abstract: | In order to analyze the error between simplifying the road sound source to one linear sound source located at the road centerline and multiple linear sound sources located at the driveway center according to the number of lanes, the error calculation formula of noise influence caused by multiple line sources and one line source at the receiving point is deduced for different width of the road, and the formula is verified by Predictor-lima software and field measurement. The results show that when the distance between the receiving point and the road edge is greater than the width of the road, it can be simplified as one linear sound source; on the contrary, it should be simplified to multiple line sound sources according to the number of lanes. |
