| Summary: | Objective In structural geology, faults and their damage zones are fundamental structural units that hold significant research and engineering value. They can be usde to reveal the evolution laws of regional structures and the evolution characteristics of fault structures, to indicate the migration paths of underground fluids, and to evaluate the stability of major engineering rock masses. However, traditional research methods often rely on manual recording to obtain information on fractures and surrounding joint structures, which suffer from inefficiency and susceptibility to limitations imposed by complex terrain. The emerging unmanned aerial vehicle (UAV) aerial survey technology in recent years has effectively addresses the limitations of traditional methods. This method integrates data acquisition, terrain mapping, and dynamic monitoring. It generates high-resolution digital models and images that can more effectively reduce field workload, more intuitively display terrain features, and more conveniently extract structural information. This method can be applied more broadly to the field of structural geology and geological engineering, especially when studying faults and damage zones. Methods Based on an extensive literature review, we categorized and compared existing research in relation to different application scenarios. Results This study provides a detailed explanation of the basic principles of UAV aerial survey technology and the definition of fault damage zones and associated structures. It also enumerates widely used methods for identifying the extent of fault damage zones and characterizing structural features. Additionally, application scenarios of UAV aerial survey technology within fault damage zones are summarized. Conclusion Overall, UAV aerial survey technology has been widely applied in the study of faults and their damage zones, meeting various research needs. However, challenges remain in both the front-end (structural information acquisition) and back-end (structural information interpretation) processes, leaving ample room for future applications and advancements. |
