PSEUDO STATIC SLOPE STABILITY ANALYSIS

Earth embankments are required for railways, roadways, earth dams, leeves and river training works. Stability of these embankments or slopes needs to be thoroughly analysed. Their failure occurs in every conceivable manner, slowly or suddenly and with or without any apparent provocation leading to loss of life as well as colossal economic loss. Failure of slope takes place due to action of gravitational forces and seepage forces within the soil. In this paper, it has been proposed to analyze stability of slope considering static and dynamic forces. However to reduce the complexity in dynamic analysis, seismic forces are converted into their equivalent static forces called as Pseudo static forces. Hence the analysis is called Pseudo static slope stability analysis. An attempt is made to study behavior of slope considering various parametric and material property variations for static as well as Pseudo static forces. A computer program was developed to validate manual calculations and facilitate calculation work. Variation of Factor of safety with respect to static forces and pseudo static forces has been studied considering various parameters. Conclusion has been drawn based on results obtained https://journalnx.com/journal-article/2015023
