In the current study, the results of numerous piezocone penetration tests performed in various locations of South Pars Gas & Oil field, Persian Gulf, Iran, were used to evaluate undrained shear strength of marine clay of the site using cone factors. Comparison of variation of undrained shear strength and PCPT results in depth was shown that cone factor can be a useful parameter to determine undrained shear strength, indirectly, from cone tip resistance. It was observed that there is a relatively strong correlation between undrained shear strength of soil and cone tip resistance. With studying the variations of cone factors in depth, an average value of Nk=18 and Nkt= 21 were proposed for South Pars field. In addition, the results were demonstrated the importance of taking the effect of pore water pressure into account for determining cone factor. Moreover, it was showed that cone factor is rather dependent to over–consolidation ratio of soil. As over–consolidation ratio increased both cone factors decreased with a descending rate<\div>

Predicting ultimate axial bearing capacity of pile foundation is an important and complicated problem in geotechnical engineering. Cone penetration test (CPT) is a reliable in–situ test, widely used in analysis and design of pile foundations.In this study, new CPT–based axial pile bearing capacity model is presented for sandy soils using evolutionarypolynomial regression (EPR), a branch of evolutionary approaches. A relatively comprehensive database is gathered and divided into training and testing sub–sets to avoid over–fitting. This database includes cone tip resistance and sleeve friction of CPTs, geometry and bearing capacity of piles. The presented model is compared to some previously published ones and its preference is demonstrated statistically and probabilistically<\div>
