摘　　要：交通噪声面波勘探在城市浅地表勘探中具有巨大的潜力,但频散信息成像质量较差。为了解决面波在城市浅地表勘探中的应用难题,提出一种适用于交通噪声的数据质量控制方法,通过信噪比数据筛选及相位加权叠加进行质量控制,有效提高了交通噪声面波频散成像信噪比及分辨率,拾取了更高精度的频散信息,应用本研究提出的交通噪声数据质量控制方法,在广州凰岗电力隧道实测数据中进行验证,取得了显著的效果。本研究方法为交通噪声面波勘探提供了一种有效的数据质量控制方法,有利于推广交通噪声在面波勘探中的应用。Traffic noise surface wave exploration holds significant promise for urban shallow subsurface investigations.However,current dispersion data is often limited by poor signal quality.To address these challenges,this research pro⁃posed a data quality control method specifically designed for traffic noise.The method enhanced signal⁃to⁃noise ratios through data screening and phase⁃weighted superposition,effectively improving the quality of the traffic noise surface waves.These improvements in signal⁃to⁃noise ratio and resolution contribute to more accurate dispersion imaging,as demonstrated by successful application to data from the Guangzhou Huanggang Power Tunnel.This research introduced a robust data quality control approach for traffic noise surface wave exploration,enabling broader use of traffic noise in surface wave investigations.
