Abstract
This paper pertains to a critical evaluation of two widely referred bearing capacity theories of reinforced foundation beds. An enhanced data-set (41 tests) have been used to carry out a refined linear and nonlinear multivariable regression analysis. The regression relations provide a statistical observational model for the prediction of bearing capacity of reinforced foundation beds. A sensitivity analysis is carried out to determine the measure of importance of the parameters towards the outcome of the model. It is found that the relative depth, number of layers of reinforcement and angle of internal friction of soil significantly influence the sensitivity of the system, while the other parameters have moderate influence. Relative length of reinforcement is found to affect the system negligibly.
