    Abstract

    This paper presents a semi-empirical approach to simplify existing CPT and PCPT soil classification charts. This approach is based on two tendencies in current charts, namely soil type and in situ soil state. These charts may be simplified into one-dimensional soil classification systems by linear conformal mapping. Accordingly, several charts are simplified, and a comparison to in situ testing data indicates the conformity of the approach and formulas suggested. The simplified systems allow users to identify and describe in situ soil types (site stratigraphy) in a visualized or graphic manner. The results also display the overlaps among different soil types in a cone soil classification.
