摘要
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FLAC3D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.
Abstract
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 electri-cal geophysical prospecting,drilling,and geotechnical testing to find out the formation mechanism,landslide mass structure and deformation characteristics of Mazhai Landslide,and used FLAC3D 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.
