Experimental and numerical analysis of rainfall-induced slope failure of railway embankment of semi high-speed trains

Abstract Safety and maintenance of railway tracks has been very crucial, for sustainable economic development many nations. Almost the entire Indian were built over raised earth embankments. These embankments are susceptible to slope failure due numerous reasons. One major cause is seepage surface runoff during rainy (monsoon) season. Erosion by gullying regarded as most significant scar. Various researches had studied embankment rainfall. However, effect on missing in these studies. Hence, this study stability analysis performed considering gullying. Embankment Dedicated Freight Corridor (India) taken up study. The present three sections (a) Field observation, (b) scaled laboratory modelling, (c) FEM-based numerical analysis. vegetation, degree compaction, intensity rainfall evaluated. Effect incorporated through change shape dimension embankment. It found that vegetation significantly reduced gully formation also less compacted experienced more gullies compared slope. While varying from 20 100 mm, it observed without consideration higher FOS (factor safety) was reported. Moreover, decrease with increase mm becomes constant after that.
