The development of a riverfront has been planned as an integral part of a Smart City Project in eastern state of India. The riverfront development project aims to improve the relationship of residents with the river, initiate sustainable growth vehicle, redefine the tourist value through glorifying the local culture and heritage and improve liveability conditions. As a pilot project, the stretch of 1.7 km of the river is considered. The slope stability analysis and stabilization of existing slope embankment on either side of the river was considered as a part of riverfront development. As part of the analysis, the geotechnical investigation has been carried out to capture the representative subsoil characterization of entire stretch of 1.7 km. Based on the geotechnical investigation report, the subsoil profile consists of a very weak soft soil extending to the depths of around 7–17 m followed by a dense to very dense sandy stratum. Micropiles of 300 mm diameter of around 25 m depth are provided for stabilization of slopes. The paper presents the discussion on the analysis and design methodology of micropiles adopted for in-situ stabilization of river slope. Based on the subsoil profile and location of structures, the slope stability analysis was carried out for chainages with weaker subsoil profile and was continued till the chainage of stronger profile was encountered. The slope stability analysis was carried out for river sections of the identified chainages in the 1.7 km stretch. All these sections are analyzed as per IS 7894 for various critical conditions like steady seepage, sudden drawdown and seismic conditions using the “GEOSTUDIO 2018” software. The slopes that failed in the stability analysis were further reanalyzed considering varying number of micropiles in iterative process till acceptable factor of safety is achieved. The embankment top was also considered to be supported with the gabion wall to attain more structural stability.
