【摘要】 瞬态多道面波勘察技术,已在岩土工程测试领域得到了广泛应用。目前,其数据采集与处理多基于单排列共炮点(CSP)的多道面波模式进行,在面波相速度频散曲线的求取中依据的主要是共炮点多道解析法。本文结合国内外同行开展多道面波法的最新研究成果,介绍了应用类似地震反射多次覆盖叠加的技术原理,在多道面波法的数据采集与处理中拓展为基于共中心点(CMP)的解析模式,探讨了其解析原理及反演过程,并分析了CMP解析法的场地试验及工程实例。最后,文章得出采用CDP叠加法的多道面波勘察数据,应用CMP解析法可以进一步提高空间分辨率的研究结论。更多还原

【Abstract】 The exploration technique of MASW has been widely used in engineering investigation. Data acquisition and processing are based on the common shot gather (CSP) model at present,and calculate dispersion curve or phase velocity,too. This paper elaborates the technique that applies multiple coverage seismic reflection method to data acquisition and processing of MASW,treats of the CMP analysis principle and inversion procedure. In the end,this paper comes to the conclusion that applying the CMP analysis method to processing the common shot gather data superposed of MASW can improve the spatial resolution and get a good prospect by site surveying test and project cases.更多还原
