Stability AnalysisandPrevention MeasuresofaLandslidein a Limestone Area

Abstract: [Purposes] This paper aims to analyze the slope stability in limestone area and put forward corresponding prevention and control measures,so as to provide reference for the same type of landslide control.[Methods] Based on the geological conditions and surrounding construction factors of a specific limestone landslide in Nanming District,Guiyang,the current stability of the landslide wasanalyzed. Two typical profiles (Sections12 and14) and two working conditions were selected for verification. [Findings] Calculations show that for Section 12, the slope safety factor is O.822 under normal conditions and O.771 under seismic conditions.For Section 14,the slope safety factor is O.898 under normal conditions and O.852 under seismic conditions.These results indicate that the landslide is in an unstable state.[Conclusions] Comprehensive protection and treatment of the slope are required,incorporating measures such as support structures,drainage,load reduction,backfilling，grouting,and vegetation.A slope monitoring system should be established,and dynamic observation implemented to ensure the operational safety of people 's lives and property.
