Abstract
The earthquake that took place at Bhuj in 2001 acted as a wake-up call that triggered
a review of the seismic risk in several areas of the nation. Seismic microzonation
analysis benefits greatly from in-depth investigations of both geotechnical and
geophysical conditions.
This study aims to create correlations between the conventional SPT-N value and
the s - wave velocity for different soil conditions in the Dahej port. For the geophysical
site characterization, the shear wave velocity models were created using the MASW
method and the bundle of software known as SeisImager/SW was used to perform an
analysis of the test results. Moreover, the correlations are compared to the relationships
established by other scientists. The suggested correlations will be beneficial for
the congested areas of the vibrant area, where testing is neither practical nor
cost-effective. Such empirical correlations will be used for other similar geological
and geophysical site conditions when they have gone through the essential validation
stages. To analyze the ground response and a hazard assessment of the study region,
the obtained correlations can be used.
