贵州省都匀市大坪镇马寨村滑坡变形破坏机制及FLAC^(3D)稳定性评价

Deformation failure mechanism and FLAC^(3D) stability evaluation of Mazhai Village Landslide in Daping Town,Duyun City of Guizhou Province

以贵州省都匀市大坪镇马寨村滑坡为例,采用地质调绘、高密度电法物探、钻探、土工试验等综合工程地质勘察方法,查明马寨滑坡形成的机制、滑坡体的结构和变形特征,并采用FLAC^(3D)数值模拟分析该滑坡体的稳定性,为下一步进行滑坡工程治理提供了可靠的依据,也为未来同类型的大型牵引式滑坡分析和治理提供借鉴。

Taking Mazhai Village Landslide in Daping Town,Duyun City of Guizhou Province as an example,this paper used comprehensive engineering geological survey methods such as geological mapping,high-density electrical geophysical prospecting,drilling,and geotechnical testing to find out the formation mechanism,landslide mass structure and deformation characteristics of Mazhai Landslide,and used FLAC^(3D) numerical simulation to analyze the stability of the landslide.This paper provides a reliable basis for the next step of landslide engineering treatment,as well as reference for the analysis and treatment of large-scale traction landslides of the same type.
