摘要

The correlation between shear wave velocity V_s and standard penetration test resistance N is investigated in Northwest Himalaya. The study focuses primarily on two sites: Dhanauri and Roshnabad in the Ganga foreland basin. The Dhanauri site comprises a mixture of clay, silt and sand, and the Roshnabad site comprises predominantly gravelly soil. A new empirical formula is suggested to correlate shear wave velocity and standard penetration resistance, based on a dataset collected as part of an earthquake risk evaluation study in the Northwest Himalayan region, India. The formula is based on geotechnical exploration (standard penetration test) and seismic experiments (multichannel analysis of surface wave). The relationship derived was compared with existing correlations in the literature.
