To develop a method for two-dimensional subsurface soil classification and layer zonation using sparse cone penetration test data without estimating horizontal correlation lengths.
Interpolated sparse vertical cone penetration test measurements across a two-dimensional section using Bayesian compressive sampling.
Assigned soil behavior types across all sampled and unsampled locations via soil behavior type charts, followed by edge detection to delineate layer boundaries.
Evaluated algorithm performance using both synthetic subsurface simulations and real-world geotechnical sounding datasets.
Bypassed the requirement to model horizontal correlation lengths while maintaining continuous two-dimensional stratigraphy identification.
Successfully identified both uniform soil stratification and complex horizontal soil zonation patterns.
Achieved robust boundary delineation and classification accuracy when evaluated with as few as five sounding profiles.
