Abstract:

In order to deal with the superposition effect of human engineering activities and natural geological processes under the complex and changeable geological environment in China, the limitations of single monitoring means in characterizing the landslide hazard evolution process was broken to realize the early identification of landslide hazards and accurate early warning of disasters. Firstly, this paper generally describes the current research status of full-dimension monitoring and early warning technology of integrated monitoring for the air, space, ground, and interior. Then from the aspects of early identification and emergency monitoring of potential hazards, multi-source and multi-dimensional integrated intelligent monitoring, cross-monitoring of new materials and new processes, and monitoring of submarine landslide based on DAS(Distributed Acoustic Sensing) technology. The achievements of theory, technology, and application in landslide monitoring and early warning in recent years are summarized. Finally, based on the limitations of various monitoring technologies, the challenges and development trends of current landslide monitoring are prospected. The research shows that various technologies' application conditions, advantages, and disadvantages are obtained through the comprehensive comparison of landslide integrated full dimension monitoring and early warning technologies. However, the difference in various monitoring technical indicators often leads to missing and miscalculating monitoring data. In the future, the research should focus on early warning criteria and system modeling.
