Abstract
Safe bearing capacity of soils is used in foundation design. Shallow foundations in
the form of continuous strips are widely used. Standard equations are available to
estimate the safe bearing capacity of soil supporting strip shallow foundations. It
appears from these equations that there is a stro
ng dependence of bearing capacity
on angle of internal friction. An attempt has been made in the present study to get
simplified correlation between safe bearing capacity of soil and angle of internal
friction using the principle of least squares. Correlat
ion has been developed by
analyzing 20 different soil samples and verified for 19 other soil samples. Analytical
equations in the form of linear as well as quadratic polynomial have been developed.
Correlation coefficient between actual and estimated value
of safe bearing capacity
for linear and quadratic polynomial was found to be 0.869319 & 0.942516.
