摘　　要：面波勘探在浅层勘探中获得了广泛应用.随着地震干涉理论和被动源噪声互相关技术的发展,发现传统的基于微动技术的空间自相关技术(SPAC)方法和背景噪声互相关函数(NCF)的物理本质是一致的,因此,将地震干涉理论用于被动源面波勘探中的技术和方法越来越受到关注.本文基于地震干涉理论和应用的发展,对面波勘探的原理进行了简要介绍,阐述了主动源方法中稳态法、瞬态法等各种常规方法.并根据最新的研究进展,对被动源SPAC和NCF方法在浅层勘探中的应用进行了评述,分析了各种勘探方法的原理和特点,叙述了主动源与被动源SPAC方法及NCF方法三者联合勘探的新思路,有望将传统的面波勘探技术拓展到浅层三维速度结构的精细探测.叙述了面波反演过程中多模式问题的一些重要概念和处理方法,最后讨论了面波方法的发展趋势和几个值得关注的研究方向.Surface wave exploration is widely used in shallow exploration. With the development of the seismic interferometry theory and the technique of Noise Crosscorrelation Function（NCF）,it was found the traditional surface wave method with passive tremor method（SPAC,SPatialAutoCorrelation）and the NCF technique have the same physical basis.Therefore,the application of seismic interferometry technique in the surface wave method based on passive source has been paid more attention.In this paper,a brief introduction of the principle on surface wave exploration is given.The steadystate and instantaneous methods on surface wave are specifically addressed.based on the development of seismic interferometry theory,the surface wave method with passive source,such as SPAC and NCF technique are summarized.The features of different methods are analyzed.The advantages and strategy on joint application of active and passive source,including SPAC and NCF,are presented.We also analyzed some terminology used in multimode surface wave method and put forward an inversion method for the model with the soft sandwich structure.In the last,we present the state-of-the-art technique on Surface wave method.
