以在上海市区开展地震调查深埋活断层的实例，讨论了在都市区强干扰条件下开展断层活动性调查的地震方法技术。认为：在对基岩断层的活动性评价中，反射纵波法根据基岩断层是否向上延伸到第四纪Ｑ３地层内，而剪切波分裂法则根据由Ｑ３地层内界面反射横波确定的各向异性。当基岩断层向第四系延伸幅度较大，即第四纪地层内断层落差较大时，可采用反射纵波法；当基岩断层活动引起的第四纪地层内的断层落差较小，反射纵波法不能对其分辨时，可采用剪切波分裂法
An example of deep buried fault in seismic survey in Shanghai urban area is discussed. Seismic method techniques for conducting fault activity survey in urban area under strong interference are discussed. It is considered that in the evaluation of bedrock activity, the reflection P-wave method extends into the quaternary Q3 formation according to the bedrock fault, and the shear-wave splitting rule is based on the anisotropy determined by the reflected shear wave in the Q3 formation . When the bedrock fault to the Quaternary extension of the larger, that is, the Quaternary strata within a larger gap, the use of reflection longitudinal wave method; when the bedrock fault activity Quaternary strata within the fault drop is small, reflection The longitudinal wave method can not be resolved, the shear wave splitting method can be used
