Srinagar metro rail is a part of the huge upcoming construction project proposed by the Government of India, aiming at the creation of a Mass Rapid Transport System in the state of Jammu and Kashmir. For this study, geophysical investigations using Multichannel Analysis of Surface Waves (MASW) have been conducted at 33 selected sites along the proposed alignment of the Srinagar metro. Shear Wave velocity profiles over 30 m depth have been generated at each location. Using the average value down to 30 m (VS30), seismic site characterization of the locations has been carried according to National Earthquake Hazard Reduction Program (NEHRP) guidelines. VS30 is an important dynamic parameter of soils which is a critical input for evaluation of the seismic response of a soil deposit to earthquakes. Site classification using average N values up to 30 m (N30) has also been carried out. The values of N30 vary between 6 and 32 along the alignment of Srinagar Metro. The range of VS30 for the sites is 139 to 451 m/s along Corridor-I, 151–410 m/s in Corridor-II and 189–428 m/s in Corridor-III. Site characterization revealed that most of the sites fall within D and E categories, with only a few sites in C category. This means that these sites are suceptible to high hazard during earthquakes. Site conditions in Srinagar City vary drastically owing to the topographic changes and influence of water bodies. It is thus imperative to conduct site specific geophysical tests for the purpose of site characterization and earthquake resistant design of structures associated with the Srinagar Metro rail.
