Statistical evaluation of selected methods in foundation engineering
In this paper, soil samples were collected from selected locations in Nigeria. Geotechnical properties were determined by using standard methods and evaluated statistically using total error (TE), model of selection criterion (MSC) and statistical reliability (SR). The study revealed that Al Khafaji and Andersland (4.947; 0.570 and 0.984); Nagaraji and Murthy (4.373; 0.606 and 0.983); Wroth and Wood (3.342; 0.694 and 0.980) and mathematical method (3.006, 0.732 and 0.980) are the best techniques for soil settlement determination based on MSC, TE and SR. It was concluded that Skempton, Acar et al and Azzouz et al techniques should be used only when approximate values are required.
