摘　　要：噪声会对建筑及周围环境产生较大影响,噪声预测和噪声控制对整个建筑噪声环境的改善有着重要的意义。以安徽省某文教建筑噪声环境为研究对象,通过现场监测和数值模拟预测对比研究的方式,分析了声屏障的设置和车流量的大小对厂界噪声环境的影响。研究结果表明,声屏障的设置使同一区域声屏障两侧的噪声值出现突变,显著降低了外部噪声源传播至另一侧的噪声值;车流量大小的改变使厂界噪声值产生波动,受外界气候地貌等影响,车流量的大小与噪声值基本呈正相关关系。该研究为今后环境噪声预测和环境噪声控制提供了一定的理论依据。Noise has a greater impact on buildings and the surrounding environment.It has a great significance for noise prediction and control to improve the environment of noise in buildings.By taking environmental noise of a cultural and education construction in Anhui Province as object of research,by using the method of field monitoring and numerical simulation,the influence of noise barriers and vehicle flowrate on the noise environment is analyzed.Results indicate that the noise values of the same area on both sides of the noise barrier are mutated.The noise emitted by the external noise to the other side is significantly,reduced,the fluctuation noise value is caused in the site by the change of vehicle flowrate.Due to the impact of external climate and landscape,basically the size of vehicle flowrate and noise values are in a positive correlation.It provides a theoretical basis for environmental noise prediction and environmental noise control in the future.
