Calculation of Pile Capacity in Cohesionless Soil by CPT Considering Spatial Variability

The study aims to construct a framework for CPT based ultimate pile capacity calculation cohesionless soils with random field theory. Cone tip resistance (qc) was taken as the spatially varying parameter constant mean and changing coefficients of variation. profiles were simulated generations, single (Qu) calculated these simulations. influence spatial variation qc on Qu investigated. proposed finally verified by comparing results an actual database in study. showed that critical vertical scale fluctuation CPT-based calculations equal one diameter (dv=1D), method effectively predicted through field. is especially recommended cases where uncertainty consideration necessary, yet site-specific data limited. contribute simple methods unceratinty consideration. propesed facilitate design limited available data.
