SLOPE STABILITY ANALYSIS WITH GEO5 SOFTWARE FOR MALIN LANDSLIDE IN PUNE (MAHARASHTRA) (2016)
In recent times the natural hazards in India & all around the world are increasing day by day. Many of the hazards are happening due do man made activities. One such example of man -made hazard is landslide. One such landslide which came under news was in Pune district in Ambegaon Taluka in small village like Malin. In Malin Landslide more than 200 people were died within a minute & the entire village banished from the map of India. Analysis of the stability of natural and manmade slopes and embankments is a difficult geotechnical task. The slope stability analysis is carried out to minimize the circumstance of failing slopes and landslides. Through proper measurement of slope stability the Slope failing can be determined. The consideration of interslice force and the complete equilibrium of the sliding mass is the main difference between limit equilibrium analysis methods. The appropriate analysis method results the effectiveness of all slope failure remediation method. The software GEO5 allows geotechnical engineers to carry out limit equilibrium slope stability analysis of existing natural slopes, unreinforced man-made slopes, or slopes with soil reinforcement. The program uses many methods such as: Bishop’s Modified method, Janbu’s Simplified method, Spencer method, Morgenstern-Price method and others. GEO5 allows these methods to be applied to circular, composite, and non-circular surfaces. The objectives are what exactly is landslide. What happened in Malin & what are the causes behind such tragedy & what can be the remedial measures to avoid landslide. This paper shows application of a GEO 5 slope stability software to evaluate stability of the Malin Landslide in Pune.
