滑坡监测数据曲线与机理研究的相关耦合关系——以云南腾冲市五合乡邦听组滑坡为例

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

摘要:

本文以云南省腾冲市五合乡邦听组滑坡为研究对象，基于地质调查、监测数据与数值模拟，系统分析滑坡变形数据曲线与地质力学机理的耦合关系。研究发现，滑坡位移响应与降雨强度、孔隙水压力变化呈现显著非线性关联，其变形机制受地层渗透性差异、人类工程活动及河流侵蚀作用共同驱动。通过构建水-力耦合模型，揭示滑坡多阶段变形特征与地质条件的动态响应规律，提出“降雨-入渗-失稳”链式预警阈值，为区域滑坡风险防控提供理论支撑与技术范式。

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.
