交通量昼夜比、车型比对道路交通噪声影响研究
|
摘要
目前,交通量昼夜比和车型比等重要参数对环境影响评价中交通噪声预测结果影响较大。为了更加准确地预测道路工程营运期交通噪声对环境的影响,采用《环境影响评价技术导则-声环境》(HJ 2.4-2009)要求的交通噪声预测模式,结合拟改建的宜春市G320国道沙田至分界一级公路的交通噪声预测,分析和讨论交通量昼夜比和车型比等重要参数对交通噪声预测结果的影响。同时,比较预测值与实测值之间的差异,对预测结果进行修正,以提高预测结果的准确性。
At present, important parameters such as day-night ratio and vehicle ratio of traffic volume have a greater impact on traffic noise prediction results in environmental impact assessment. To accurately predict the impact of traffic noise on the environment during the operation period of the road project,this paper adopts the traffic noise prediction model required by the "Technical Guidelines for Environmental Impact Assessment-Acoustic Environment"(HJ2.4-2009), combined with the planned reconstruction of the Shatian-fenjie first-class highway of the G320 National Highway in Yichun City. The study will analyze and discuss the impact of the important parameters such as the day-night ratio of traffic volume and the vehicle model ratio on the traffic noise prediction results. At the same time, the difference between the predicted value and the measured value is compared, and the predicted result is corrected to improve the accuracy of the predicted result.
