天—地协同调查滑坡灾害的方法研究
Research on Methodology of Sky-Earth Collaborative Investigation of Landslide Disasters
摘要
Abstract
Taking a mega landslide area in Guangdong Province as an object,this paper innovatively adopted a sky-earth synergistic three-dimensional investigation method,integrating the application of ground-penetrating radar and three-dimensional oblique photography to carry out a comprehensive investigation and analysis of landslides.Ground-penetrating radar utilized high-frequency and low-frequency dual-channel antennas to detect the underground structure and sliding surface characteristics,and revealed the fissure development and hydrological characteristics of the landslide body.Three-dimensional oblique photography visualized the surface morphology of the landslide area,the distribution of the fissures,and the sliding characteristics through the high-precision three-dimensional model.The results show that the joint application of the two technologies effectively compensates for the limitations of a single means,realizes the organic integration of surface and underground information,and can accurately reveal the spatial structure and sliding mechanism of landslides,providing a scientific basis for the monitoring and early warning of landslide hazards and prevention and control measures.The multi-technology joint investigation method proposed in this paper has high practicality and popularization value,and can provide reference for the comprehensive study of geological disasters.关键词
