Abstract
Standard Penetration Test (SPT) is a very common situ test all over the world for its simplicity.
Whereas Cone Penetration Test (CPT) is recently getting popular for its accuracy. Both the tests
are necessary for the study of stratigraphy of soil and to find out important geotechnical
properties of subsurface soil. Many empirical studies have been conducted based on the
correlations of parameters of the two in-situ tests. Dhaka soil is mostly sandy with a mixture of
silt and clay. In this study, correlation among the sleeve friction, cone penetration resistance
from CPT and N value from SPT. The n ratio for Dhaka soil was compared with those from
other literatures. Also, Multiple Linear Regression Analysis has been done with the help of
MATLAB for the generation of N-value prediction multi-linear equations for various soil types.
Verifications of the N value prediction for sandy Dhaka soil shows that the study requires some
improvements that addition of fine content is to be done.
