At present,the precision of urban hidden faults is increasingly required.However,in the work area with thick cover layer and shallow upper break point,it is difficult to accurately depict the upper break point by using P-wave reflection method alone.Taking engineering practice as an example,combining the advantages of shear wave reflection method in high-precision shallow seismic survey,this paper adopts longitudinal and shear wave seismic reflection method to realize high-precision fault survey.The practical application results show that it is an effective way to obtain high-resolution shallow seismic survey by first identifying the distribution of strata above the bedrock and the location of larger scale breakpoints by seismic P-wave reflection method,and then more accurately identifying the stratigraphic characteristics of shallow overlays and smaller scale shallow faults by seismic S-wave reflection method.
