Modernization demands enhanced infrastructural development in every corner of any nation. The integrated road network in the hilly area itself is a big challenge. Construction of tunneling projects tends to increase the road network connectivity in hilly terrain. This improves traffic capacity, which enables frequent mobility of transport systems. A case study of vulnerable tunnel approach passing through tectonically active multi-folded rock mass of young mountains in Rohtang region has been discussed. An estimated 8.8 km long Rohtang tunnel (NATM tunneling) was proposed passing through a diversified geological sequence of uniform dipping rocks having quartzite, quartzitic-schist, and quartz-biotite schist with a thin band of phyllites creating high-stress flow due to overburden. Deep-seated complex failure has been observed at this location. Tunnel squeezing and rock bursting occurred due to explosion, redistribution of elastoplastic pressure during tunneling works. The jointed rock is having an NW-SE joint strike with 220/35° dip direction having three joint sets. In this case study, stability of around 200 m of affected scarp zone has been addressed using the FEM technique. Mohr-coulomb and Generalized Hoek- Brown parameters have been defined for overlying mass and underlying weathered, jointed bedrock strata respectively. Squeezing and exceeding tangential stresses at the periphery of tunnel area as compared to unconfined strength of near lying disturbed rocks resulted in a high concentration of stresses at tunnel approach. Considering all these aspects, micro piles are used at intermediate levels below the road level with pre-stressed cable anchors at the tunnel passage level. Consequently, an increase in strength reduction factor of 98 percent and 80.9 percent has been observed under static and seismic conditions respectively. Control of massive displacement is a major concern for this critical location. FEM analysis shows that stress displacement vectors have been controlled up to 84 percent using stabilization techniques of cable anchors and micro piles.
