The fault fracturezone has a significant impact on the progress and safety of tunnel construction, and it is necessary to determine the specific location and lithology information of the fault zone before construction. In order to ensure the smooth excavation and excavation of tunnels in the project, a combination of drilling and coring, natural source surface wave method, and comprehensive logging exploration methods were used to explore the specific characteristics of fault zones under complex geological conditions, and to conduct experimental analysis on their rock properties. The results indicate that under large-scale detection conditions, the natural source surface wave method can comprehensively survey the approximate characteristics of fault zones, and preliminary fault localization can be carried out based on the characteristics of wave velocity changes.The comprehensive logging method accurately identifies the specific location and distribution of faults based on parameters such as resistivity and natural potential, and provides quantitative analysis of the position, width, attitude, composition, cementation degree, and water content of fault zones. The combination of multiple methods improves the accuracy of fault fracture zone detection.
