摘　　要：结合福鼎至宁德高速公路工程竣工环保验收的工程实例,对该公路营运初期交通噪声实地监测,用回归曲线的方法,从垂直和水平方向分析了高速公路沿线两侧交通噪声声场分布及其交通噪声的衰减规律,分析了交通噪声对处在不同地理位置上敏感点的影响程度。从噪声治理技术的角度,提出了营运期公路交通噪声污染有效治理的合理化建议。On the basis of working experience from Fuding-Ningde Expressway and on-the-spot test monitoring of traffic noise;with regression curves,it is studied that the sound field distribution and the declining trend of traffic noise at either side of the expressway vettically and horizontally,the paper analyzed the effect of traffic noise at sensitive points in different locations,the effective remedy for the traffic noise pollution is recommended.

关 键 词：交通噪声 噪声监测 噪声治理 高速公路
