Slope Repairing Methodologies in Railway Embankment

The generalized methodology of slope repairing for railway embankment considering several case histories in northern India is presented in this paper. There are many available literatures to assess the reason of recurring slope failures and its preventive measures form construction point of view. However, there is no synthesized practical recommendations to overcome the issues of recurring slope failures and address the common methodology for already failed slope repairing system. The present study focuses on the slope repairing methodology under different scenario of rain-cut problems. The common issues are rainfall infiltration, slope height, soil types, fines content, level of compaction, etc. Slope stability analysis has been performed for the respective sites with the already failed slope conditions to understand the requirement and utility of slope repairing techniques. About 7000 km of Indian railway track has been built on the weak formation it’s inevitable to have slope failure and the high demand of high-speed railway track also support the requirement of long-term stable slope repairing methodology. Several case histories of the already failed railway embankment slopes have been discussed along with the proposed repairing techniques. The generalized methodology of the slope repairing techniques has been suggested considering all the aspects.
