Landslide monitoring data curves and coupling mechanisms of deformation processes： A case study of the Bangting Formation landslide in Wuhe Township， Tengchong， Yunnan Province

Abstract:

This study investigates the Bangting Formation landslide in Wuhe Township， Tengchong City， Yunnan Province， China， systematically analyzing the coupling relationship between landslide deformation data curves and geomechanical mechanisms through geological surveys， monitoring data， and numerical simulations. The research reveals a significant nonlinear correlation between landslide displacement responses and rainfall intensity as well as pore water pressure variations， with deformation mechanisms driven by stratigraphic permeability differences， human engineering activities， and river erosion. By constructing the hydro-mechanical coupling model， the multi-stage deformation characteristics of landslides and the dynamic response law of geological conditions are revealed， and the "rainfall-infiltration-instability" chain early warning threshold is proposed to provide theoretical support and technical paradigm for regional landslide risk prevention and control.
