Abstract

In thin overburden area,the application of shallow P-wave reflection to fault detection can only obtain the reflected waves of the bedrock top surface,but it is difficult to accurately determine the location and buried depth of the fault.In this paper,the authors first applied shallow P-wave reflection method to obtain the approximate location and buried depth of the fault,then used ultra-shallow S-wave reflection method to confirm the location and supplement the shallow fault information.Through the joint detection, more reliable localization of the fault plane position was achieved,and more abundant structural feature information of faults ranging from shallow to ultra-shallow depths was obtained.On the basis of joint detection,the drilling exploration composite geological section was arranged to verify the existence of the fault.The results show that the P-wave and S-wave joint detection of buried faults in thin overburden area is more effective than a single method.It can obtain more fault information and can provide a more reliable basis for the layout of drill exploration composite geological section.

Key words： thin overburden area shallow P-wave reflection ultra-shallow S-wave reflection joint detection
