ASSESSMENT OF SLOPE STABILITY OF EARTH DAMS

The first and foremost requirement for the analysis and design of earthen dams is to guarantee their safety and reliability during their service life. Therefore, regular and thorough inspections and measurements of water constructions are carried out to track movement of slopes, which serve as data used in stability calculations. Earthquakes are random events, so their occurrence in the areas never hit before or hit but of different intensity cannot be precluded. Therefore, structures of greater significance must be analyzed and verified for the effects of seismic actions. The paper target is the appraisal of the slope stability of the water construction in four cross profiles and review of the consequential stability grade. The GEO 5 software for the slope stability is the essential component of the work. The critical factors of safety have been determined by Bishop and Sarma methods for Domasa dam.
