The widening of National Highway is being done for all-weather road of “Char Dham Highway Development Project.” Due to road widening, some locations on the NH-34 have become vulnerable to landslides and erosion and requires maintenance with protection and erosion control measures to protect the road formation and hill slopes. One such critical zone has been identified between Ch. 121.340 km to 121.540 km which became vulnerable to landslides as the slope is exposed due to cutting for road widening. The area is prone to heavy rainfall and seismic activity falling under Seismic Zone V. Rockmass present in the area is quartzitic rock of meta-sedimentary origin bounded by two major litho-tectonic units. A perennial Gair Nala is flowing at the toe of landslide. The complexity of geology and influence of tectonics could be the reason of fragile nature of rockmass and frequent sliding event in the region requiring maintenance with protection and erosion control measures to protect the road formation and hill slopes. In the present work, investigating the criticality of the terrain and location of project, it has been proposed to provide shotcrete sandwiched with the chain link mesh (applicable for a height of 18.5 m above existing Random Rubble Masonry Wall) and flexible fascia with Techrhombus (High Tensile Rope Net System) with secondary Double-Twisted (DT) mesh along with soil nailing (applicable for a height of 10 m above shotcrete level) for a stretch length of 95 m. Geo-synthetic Cementitious Concrete Mat (applicable for a height of 47 m) along with soil nailing is proposed to stabilize the slope and to prevent dislodging of surface strata/loose blocks for a stretch length of 105 m. Additionally, CC gravity wall of 4 m height with lateral and vertical anchors of 6 m length are proposed for a stretch length of 20 m for toe stability and erosion control. Simulation of the proposed solution was carried out with SLIDE software and the targeted factor of safety is achieved in static and seismic conditions.
