The glacial debris flows in the Yarlung Zangbo River basin in southeast Tibet exhibit significant scale, prolonged duration, and substantial impact. The glacial debris flow in the Yarlung Zangbo River basin in southeast Tibet is large in scale, long in duration and strong in impact. The study of the deformation characteristics and influencing factors of the Sangugou debris flow provides a scientific reference for the prediction, early warning and prevention of glacial debris flow disasters in southeast Tibet. Since the traditional method is difficult to describe the formation mechanism of large-scale debris flow quantitatively, the field investigation of debris flow in SangguValley Valley, UAV aerial photography, satellite image information and geological and meteorological data are used,
Reveal the relationship between the outbreak of debris flow in SangguValley and factors such as material source and rainfall,
A new method combining InSAR and RAMMS techniques is proposed to analyze the deformation process of debris flow before and during debris flow eruption. Based on SBAS-InSAR technology, the deformation of SangguValley debris flow during two outbreaks was analyzed, combined with satellite image, UAV image and field investigation, the deformation process inversion and disaster trend prediction were realized before SangguValley debris flow disaster. RAMMS debris flow numerical simulation software is used to simulate the movement process of SangguValley debris flow during the eruption,
The research shows that: (1) The LOS deformation of SangguValley debris flow was calculated by InSAR technology, and the slope was in a creep state for a long time; The maximum deformation rate in the source area is 139 mm/a, the maximum deformation rate in the flow area is 46 mm/a, and the maximum deformation rate in the accumulation area is 20 mm/a. Rainfall provides a lot of loose sources for debris flow development. (2) The evolution process of the study area is divided into three stages: initial motion, accelerated motion, deceleration and final motion according to the accumulation depth and velocity of debris flow under the state of asynchronism.
This method, combined with the historical analysis of glacier debris flow deformation and the simulation of movement process, provides a scientific basis for the development trend and prediction of debris flow, and provides a reference for engineering control design.
