Abstract
In this paper, an attempt has been made to propose a generalized correlation between shear wave velocity (Vs) and SPT-N values for all soil types for generalized depth using the concepts of regression. Around 40 correlations have been compiled and applied for estimating the shear wave velocity (Vs) correlation for the region and also to address the uncertainty issue. The generated correlation is then used for the computation of Vs for one-dimensional (1D) ground response analysis at two different site locations in Indore region. 1D ground response analysis is performed using DEEPSOILv6.1. Soil profiles at site taken as input for analysis were collected from 245 boreholes at 26 different locations in the Madhya Pradesh region (one of the central states in India), and it can be concluded that Vs–N correlations estimated after reducing the errors applying the multilinear perceptron and generalized regression neural network models using MATLAB coding gave better results over the linear regression analysis applied for the site-specific ground response analysis.
